Error When Saving OnePager File

In rare cases, when you are trying to save a OnePager file, you may see an error message like this:

Error 100 Error 200 Error 300 Error 400 Error 500 Error 600 Error 700 Error 800 Error 900 Error 1000 Error 1100 Error 1200 Error 1300 Error 1400

The message will read something like "Project view has not been saved as Unknown (Error 1100)". The error number can vary, but the overall message is the same. The cause of this error is a Windows issue, either with permissions or with security.

When you save a OnePager file, regardless of the destination folder you have chosen, OnePager always saves a temporary file here:

C:\Users\[yourname]\AppData\Local\Chronicle Graphics\OnePager\temp\_temp.cab

If you can't save or decompress that temporary file, the save process will abort with an error like the one shown above, and the file will not be saved.

In other words, regardless of where you are trying to save files, you need to:

  1. Have write access to the temporary folder; AND
  2. Be able to compress and decompress CAB files

If one or both of these permissions are disabled by your system administrator, OnePager will not work properly.

Restoring Write Permissions

If you generally have permissions to other folders on your computer, you can follow these steps to try and restore the correct permissions on your own. If your system is completely locked down, you may need to ask your helpdesk to complete these steps for you.

  1. Don't close OnePager! If you do, you will lose your unsaved work.
  2. Navigate to the OnePager application folder:

    C:\Users\[yourname]\AppData\Local\Chronicle Graphics\OnePager\
  3. Right-click on the Temp subfolder, click Properties, and then go to the Security tab:

    Folder is set to read only, as write permissions are being denied.
  4. Click on your name, and examine the Write permissions for your username. In example above, you will see that the Deny column has a checkmark in it, indicating that write permission to the folder is denied for your Windows user account.
  5. Click the Edit button to correct your permissions.
  6. On the second screen that pops up, you need to re-select your username, and then scroll down and uncheck any Deny boxes.

    Restore write permissions
  7. Click OK and you should immediately be granted the correct permissions that you need for OnePager to succesfully save files.
  8. You can now return to OnePager, and successfully save your file.

Again, these steps generally require administrator-level permissions on your computer, so if you are unable to complete them on your own, please contact your helpdesk for assistance.

Restoring Compression/Decompression Permissions

OnePager relies on two standard Microsoft compression utilities that closely resemble the WinZip utilities. These two utilities are shipped by Microsoft with every Windows release and are called MakeCab.exe (compresses) and Expand.exe (decompresses). If MakeCab.exe has been disabled on your computer, you will not be able to create TAM or TAT files. If Expand.exe has been disabled on your computer, you will not be able to read TAM or TAT files into OnePager.

Before trying to restore these Windows compression utilities, it's a good idea to run a quick test to see if this is your problem:

Testing for a CAB File Compression Issue

  1. Download the zipped file MakeCabTest.zip
  2. Create a folder on your desktop and expand MakeCabTest.zip so that three files are in the folder. They will look like this:

    Test of cab compression; Before
  3. Double-click on the file MakeCabTest.bat to run the diagnostic test.
  4. If MakeCab is working on your computer, the contents of the folder will change to this after less than 5 seconds:

    Test of cab compression; Before
  5. If the three additional files do not appear, it means that MakeCab is missing or disabled on your computer. You then need to ask your IT department to re-enable both MakeCab.exe and Expand.exe. Instructions for restoring MakeCab.exe are in the next section; restoration of Expand.exe follows a similar process.

Enabling MakeCAB

The ability to make compressed CAB files is controlled in the Windows Registry, but it's sometimes disabled by your anti-virus software. Before making changes to your registry, double-check to make sure that Norton, McAfee, or whatever anti-virus software you are using has not disabled MAKECAB.EXE, since it's usually easier to change your anti-virus settings than it is to change the registry.

If you don't see that your antivirus is blocking MAKECAB.EXE, you can re-enable it through the registry:

MakeCAB registry setting for cabinet compressed files.

The registry entry in question is HKEY_CLASSES_ROOT\CLSID\{0CD7A5C0-9F37-11CE-AE65-08002B2E1262}. If this registry entry is missing or otherwise disabled, it means that you do not have access to compress CAB files, and need to restore this access. Your IT department may have its own utilities to do this, but you can also fix the missing registry entry:

  1. Download and run this registry patch, called enable-cabinet-files.reg. You will need administrator permissions to run this file.
  2. Completely restart your computer.
  3. Launch the Windows Registry Editor (regedit), and double-check that the registry entry now appears as shown in the screenshot above.
