When attempting to launch OnePager, you may receive a warning from Microsoft Office stating:
This error message is not coming from OnePager. Rather, the error message is coming from Microsoft Office, and it is indicating that you have an issue with your installation of Microsoft Office that is blocking OnePager, and likely many other apps, from starting.
OnePager versions 7.0.14 and later will detect most cases where a Microsoft component is missing or incorrectly configured and will automatically switch to a different, non-Microsoft driver that is more stable.
If your maintenance subscription is current, you can upgrade OnePager, installing any version of the application 7.0.14 or later. For the vast majority of users, simply upgrading to a newer version of OnePager will immediately resolve Microsoft's issue.
Point OnePager to an Alternate Driver
In almost all cases, OnePager will automatically detect the bad Microsoft driver and will repair itself. However, in rare cases, you may need to tell OnePager to use a non-Microsoft driver. To do this, open your registry editor, and navigate to:
Locate the DatabasePolicy setting, double-click it, and change its value to 2:
If you don't have a UserSettings folder in your registry, then your installation of OnePager may not have finished successfully. We have a registry script that you can use to make the necessary registry change manually if needed. To use it, right-click on the script that pertains to your edition of OnePager, save the file to your desktop, and then double-click it to run. Please note that running registry scripts may require administrative permissions, so please check with your helpdesk before proceeding.
Once you have changed your registry, restart your computer. The next time you launch OnePager, it will automatically switch to the more stable driver, and you will no longer receive the Microsoft warning message about your operating system.
Reinstalling the Missing Microsoft Driver
If you are unable to upgrade OnePager or switch the driver through your registry, you can sometimes resolve the issue by reinstalling the broken Microsoft driver.
Download and install the version that matches your installation of Office:
IMPORTANT: You need to download the version that matches your installation of Office, which is NOT ALWAYS THE SAME as the version of Windows you have. To double-check the bitness of Office, go to File > Account > About Project (or About Excel). You will see either 32-bit or 64-bit noted next to the Office version number.
Once installed, reboot your computer, and see if you are able to launch OnePager without Microsoft giving the same error. If you continue to receive the error after reinstalling the missing driver, you will need to proceed with changing your Microsoft Office version to one that is not broken.
Repairing Microsoft Office
In the very unlikely event that you upgrade OnePager, install the Microsoft driver, switch to the non-Microsoft driver, and still have the same issue, you can follow these steps to repair your existing installation of Microsoft Office.
In Windows, go to Start > Settings > Apps
Find Microsoft Office in your list of installed apps, and click Modify:
Perform a Quick Repair. This takes less time than the Online Repair, and is less likely to exacerbate any other issues that you might already be having with Microsoft Office.
After completing the Quick Repair, restart your computer, and then restart OnePager.
