OnePager Bundle Readme

Getting Started

OnePager® Bundle is both a stand-alone desktop application that works with Smartsheet, Planisware, Primavera P6, Asana, Wrike, and Microsoft Project for the Web, plus a COM Add-In for Microsoft® Project and Microsoft® Excel. Once OnePager has been successfully installed, its launch icon appears on the desktop and under OnePager in the Start menu. In addition, its two launch buttons appear on the “Add-Ins” ribbon of Microsoft Project and Excel. The simplest way to launch OnePager is to double-click on the OnePager icon on the desktop. This will be the best way to access data you have in Smartsheet, Planisware, Asana, Wrike, Project for the Web, or in a Primavera P6 XML/XER file. Alternatively, to launch OnePager as an Add-In to Microsoft Project or Excel, open that application and wait for it to show the OnePager launch buttons. Click on the leftmost button to make a OnePager Gantt chart or timeline from the current data source.

Edit this Gantt chart in OnePager and then save it by going to File > Save. Output the graph by clicking the “Copy” button on the OnePager toolbar. Then paste it into PowerPoint or other Windows applications.

A template sets the starting properties and imported columns when a new chart is created. Changing a template does not affect a chart after it has been created, but is a handy way to standardize many charts to look the same. To edit or create a template, just double-click on any TAT file. You can find a set of TAT files in the folder \MyDocuments\OnePager Bundle\Templates.

Every chart is stored in a TAM file, and each template is stored in a TAT file. These files are stored in \My Documents\OnePager Bundle\ by default.

Identifying the correct version of OnePager for your environment

If you install OnePager using the ‘Smart Installer’ (which is an EXE file with this icon ), you do not need to worry about this section at all, because the Smart Installer will figure everything out and install the correct version for you. If you need to package an MSI file for installation, you must choose the appropriate provided MSI file from a list like the one shown below.

OnePager is available in both 64-bit and 32-bit versions, because the 32-bit versions of Microsoft Project and Excel require 32-bit OnePager and the 64-bit versions of Microsoft Project and Excel require 64-bit OnePager.

It is the bitness of Microsoft Office that counts, not the bitness of Microsoft Windows. Note that many computers have 32-bit Project/Excel installed on 64-bit Windows. In this case, you still need 32-bit OnePager, which matches the bitness of Project/Excel rather than the bitness of Windows. You can determine the bitness of Office by going to File > Help > About Microsoft Project/Excel (Project/Excel 2010), or File > Account > About Project/Excel (Project/Excel 2013 and higher).

Supported platforms

OnePager Bundle requires Microsoft® Windows XP SP3, Vista SP1, Windows 7, Windows 8, Windows 8.1, Windows 10, or Windows 11. It also requires the Microsoft® .NET Framework 4.7.2 or higher. If .NET 4.7.2 is not installed on the target computer, you can download it for free from Microsoft® by browsing to www.microsoft.com/downloads and entering “.NET Framework 4.7.2” in the search box.

As mentioned above, OnePager runs on both 32-bit and 64-bit versions of Microsoft Windows, and with both 32-bit and 64-bit versions of Microsoft Project or Excel.


To install OnePager, double click on the ‘Smart Installer’ file, which is an EXE file with this icon . If you need to install explicitly from an MSI file, you can alternatively use a ZIP file that we provide on request. Extract the contents of the ZIP file, and run the correct OnePager MSI file by referring to the table in the previous section. Either the Smart Installer or an MSI file will install the OnePager program, its data files, and the registry keys that are required for it to work as a COM Add-In. The User Guide and other documents are also installed and are always available under the OnePager Help menu.

Per-User Installation

OnePager is installed by default on a per-user basis. This can be changed in the Windows Installer GUI, where a choice is given between installing for “Just me” (per user) or for “Everyone” (per machine). If installed for per-user, it should be installed in the account of the individual end-user who intends to use OnePager, not into an admin account that only privileged users can access.

Per-Machine Installation

OnePager can also be installed on a per-machine basis in one of two ways. The first is by selecting “Everyone” on the third screen of the Windows Installer GUI. The second is by setting ALLUSERS=1 on the Windows Installer command line or in a Windows Installer transform. Per-machine installation is recommended for “no touch” deployments that are pushed out from a central location to the end-users’ computers. To install per-machine via the command line, extract the correct MSI file from the zip file. (Note: edit the line below to put the actual name of the MSI file in place of the example opPkg.msi shown below.) Then execute the following command line on each target computer:

msiexec /i opPkg.msi /qb+ ALLUSERS=1

In a per-machine installation we put data files in locations such as C:\Program Files and C:\ProgramData, and put registry keys in the local-machine registry hive (HKLM). During installation, writing to these file and registry locations generally requires elevated privileges. Once the installation is complete, the end user of OnePager needs only read/execute access to these locations.

Launch Options

The third screen of the Windows Installer GUI also gives you a choice of how you want to launch OnePager. The default is to allow OnePager to be launched either as a COM Add-In from Microsoft Project and Excel or as a standalone application with its own desktop icon. If you prefer to launch OnePager only as a standalone application for use with Planisware, Primavera P6, Smartsheet, Asana, Wrike, or Project for the Web, choose the second radio button, which will prevent OnePager from appearing inside Microsoft Project or Excel as an Add-In. To enable the Add-In option after choosing the desktop-only option at installation, see these instructions.

Virtual Desktops

If you are installing OnePager into a virtual-desktop environment, you should do a per-machine installation on the master machine that will serve as the source image for the virtual desktops. If you are planning to have the virtual desktops access OnePager as a COM Add-In, it is recommended you launch Microsoft Project and Excel once on the master machine to cause the transfer of OnePager registry keys, data files, and binaries to a user account. You can confirm this by observing that the OnePager tutorial launches and that the OnePager buttons appear in both Microsoft Project and Excel.

Verifying Correct Installation

For any type of installation technique, here is how to verify that all components were correctly placed on the target computer:

(1) Login to the user’s account and confirm that OnePager appears in the list of installed programs in the Control Panel, on the user’s desktop as an icon, and in the Start menu under All Programs>OnePager. If you have chosen to have OnePager also launch as an Add-In to Microsoft Project and Excel, the OnePager buttons should appear on the Add-Ins tab of both ribbons. If not, this guide on our website gives steps to resolve the problem. Normally the OnePager tutorial will appear the first time that the OnePager buttons appear in Microsoft Project and Excel. Clicking through the first 3 steps of this tutorial gives a good validation that the installation has completed correctly by building a sample output from a sample Project or Excel file.

(2) For verifying standalone launch of OnePager, simply double-click the OnePager icon on the desktop. For verifying Add-In launch, press the “OnePager” button on the Microsoft Project or Excel ribbon to launch OnePager. If an error occurs in either case, make sure that the OnePager database file (DefaultDB*.t_d) is installed in the OnePager data folder referenced in the current-user hive of the registry for the user who is running OnePager:

HKCU\Software\Chronicle Graphics\OnePager Bundle\CGDataPath

Upgrade process

Installing OnePager per-user causes an older per-user version to be to be automatically removed before the new version is installed. Likewise, installing OnePager per-machine causes an older per-machine version to be automatically removed before the new version is installed. Alternatively, you can remove the older version by running the msi file in uninstall mode or by specifying the product code of the older version to be removed. When installing per-machine over an older per-user installation or when installing per-user over an older per-machine installation, it is recommended that the older version be removed manually before installing the newer version.

The user’s license key is automatically migrated from old version to new version.

There is no support in Windows for automatic downgrade from a newer version to an older version, so the newer version will need to be removed manually before installing the older version. In downgrading, the older version will not be able to read any TAM or TAT files that were created or edited in the newer version, unless they were explicitly saved in the older version’s format.

Manual removal

To remove OnePager, go to the Windows Control Panel and select “Programs and Features.” Find OnePager in the list and click the Remove button. For removing OnePager in a “no touch” environment, you can execute the following Windows Installer command on each target computer:

Msiexec /x opPkg.msi


There are three types of OnePager licenses, and one type of license can be converted into another type without reinstalling OnePager.

1. Time-limited trial license, which last 15 days from first use This free trial (or grace period) is automatically provided to you the first time you install and use OnePager. We can also extend the duration of these temporary keys after installation if you need extra time in your purchase evaluation. If you need assistance with these keys, please send your name, company name, email address, and phone number to us at [email protected].

2. Standard single-user license, valid for unlimited time for a user on a single computer After purchasing OnePager, you can convert your trial license into a standard license, with no need to reinstall OnePager. To get your license key, launch OnePager, and from the OnePager Start form choose “Help”, then “Get Standard License” and finally click “Request License Key” button on the licensing form. This takes you to our website, where you can complete your request by providing your name, email, and purchase information. We will look up your purchase and email your key within 4 business hours. When your receive your license key email from us, return to the licensing form that contained “Request License Key”, copy/paste the license key into the text box, and press the “Activate License” button. You will then see confirmation that you have a valid license key that will remain in force as long as you are on that computer.

3. Enterprise license, valid for multiple users on multiple computers in an organization Companies that purchase an enterprise license will receive a company-specific enterprise license key that works for more than one user on their internal network. You can distribute an enterprise key in “no touch” fashion to all entitled users by supplying the CGKEY parameter on the Windows installer command line or transform. In the example below, the (fictitious) enterprise license key “abcdefg==” is distributed to all entitled users in the organization during a per-machine installation from a central location:

msiexec /i opPkg.msi /qb+ ALLUSERS=1 CGKEY=abcdefg==

When the entitled user launches OnePager the first time after CGKEY has been pushed to his computer, the license activation process requires that the computer be on the network. After this activation has succeeded, subsequent launches of OnePager will not require network connectivity. If you prefer not to push CGKEY to entitled users at installation time, each entitled user can enter the enterprise key and activate his license in the same way as standard single-user licenses (see above).

Changing versions of Microsoft Project or Excel

OnePager does not need to be reinstalled if you change to a different version of Microsoft Office or if you simply want to reinstall Office. None of the OnePager data is stored in Project or Excel folders, so it persists across all configuration changes to Office. However, if you switch from 32-bit Office to 64-bit Office or vice-versa, you will need to uninstall and reinstall OnePager to affect that change.

Re-imaging or replacing a computer

If you re-image a user’s computer or migrate her to a new computer, make sure you preserve the OnePager charts (*.tam) and templates (*.tat) that she has created. These files are stored as ordinary files under the root working folder, which is \My Documents\OnePager Bundle\ by default. Just make sure that this working folder and its contents are transferred from the old machine to the new/re-imaged machine. If you want to put these files in a different directory, you can change where OnePager looks for these files by launching OnePager and going to File>Options.

To change the root of the working folders at install time, just specify a different folder in the Windows Installer GUI or execute the command line below, specifying WORKINGDIR:

msiexec /i opPKG.msi WORKINGDIR=c:\myData\OPBundleWorkingDir\

Registry keys and values

When OnePager is installed as a COM Add-In, it is vital that Microsoft Project and Excel find the OnePager program when they start up. Otherwise the buttons that launch OnePager will not appear on the ribbon. Microsoft Project discovers OnePager by using the following key, where CG_MSP_Addin.OnePagerBundle is known as the COM programmatic id (ProgID) for OnePager:

HIVE\Software\Microsoft\Office\MS Project\Addins\CG_MSP_Addin.OnePagerBundle

Here HIVE=HKCU for a per-user installation and HIVE=HKLM for a per-machine installations.

Likewsie, Excel discovers OnePager by using the following key, where CG_XL_Addin.OnePagerBundle is known as the COM programmatic id (ProgID) for OnePager:


These keys are placed in the registry during the OnePager installation process. Under these keys, LoadBehavior=3 causes the OnePager buttons to appear every time Microsoft Project and Excel are launched. LoadBehavior=2 means either that the user has disabled the OnePager Add-In or that an error has occurred when Project or Excel attempted to load OnePager.

OnePager places a second key and value in the Windows Registry to store the path name where the data folder was installed. OnePager uses this path name to find its data:

HIVE\Software\ChronicleGraphics\OnePager Bundle\CGDataPath

Turning OnePager Add-In Off Without Uninstalling It

You can turn the OnePager Add-In off and on again so that it is there only when you need it. To turn it off, go to the COM Addins form following these instructions, uncheck the checkbox next to OnePager, and press OK. To turn it on again, go to the same COM Add-ins dialog box, re-check the OnePager checkbox, and press OK.


If the OnePager buttons do not appear in Microsoft Project or Excel, check our support website for troubleshooting tips. Sometimes Microsoft Project or Excel disables OnePager, and this can be easily addressed by re-enabling OnePager. For details, read this troubleshooting guide.
