Missing Microsoft Database Driver

In some cases, a Microsoft driver that OnePager uses can be missing from your computer, or can be installed in a way that OnePager cannot see it. In these cases, you will receive a prompt to install the driver like this:

Microsoft database drivers that 64-bit OnePager needs are missing! Click the link below to install the missing 64-bit Microsoft Drivers, and then relaunch OnePager. Access DB or Access Database drivers are missing or misconfigured.

In some cases, following the prompts and installing the missing driver will fix the issue. However, if you have already installed the correct driver and are still receiving prompts that it is missing or not configured correctly, there are additional steps that you can take to resolve the issue permanently.

Upgrade OnePager

OnePager versions 7.0.12 and later will detect most cases where a Microsoft component is missing or mis-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 7.0.12 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 the 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 directly to use the alternate driver. To do this, open your registry editor, and navigate to:

Computer\HKEY_CURRENT_USER\SOFTWARE\Chronicle Graphics\OnePager\UserSettings

Locate the DatabasePolicy setting, double-click it, and change its value to 2:

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 will no longer prompt for you to reinstall anything from Microsoft.

Repairing Office

If you are unable to update to a newer version of OnePager, you will need to repair Microsoft Office in order to address the driver issue.

  1. In Windows, go to Start > Settings > Apps

  2. Find Microsoft Office in your list of installed apps, and click Modify:

  3. 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.

  4. After completing the Quick Repair, restart your computer, and then restart OnePager.

  5. If the Quick Repair does not address the issue, your IT department may need to uninstall and then reinstall Office, but this is very uncommon.
