Uninstall the conflicting version of Office

If you’re running an MSI-based Office suite, such as Microsoft Office 2013, you’ll run into problems if you try to update it with the Click-to-Run installer.

Typically, you should get an error notifying you that your current edition of Office isn’t compatible with the update you want to install. However, there are cases where error 30088-26 appears for the same problem.

If you want to switch to the Click-to-run edition, you must completely uninstall your edition of Windows Installer (MSI).

Follow these steps to remove the program:

Perform a clean boot

The clean boot technique is used to find startup programs and services that interrupt certain processes. Startup items are designed to start after Windows starts. While some startup applications stop running after executing certain instructions, others continue to run in the background.

If the error still appears, continue with the next guide.

If the update process runs as it should, then one of the startup programs you disabled is the culprit.

Enable the first program on the list and reboot your system to check if the error appears again. If the first program doesn’t trigger the error, move on to the second and then check the other programs until you find the responsible program.

Here’s how to disable startup services:

  • Use the logo of Windows + R keyboard combination to open the dialog Run or right-click the Start button and click Run.
  • After Run appears, type “msconfig” and click OK.
  • After the System Configuration window appears, go to the Services tab.

  • Click the button disable all.
  • Then click To accept and restart your computer.
  • Once the system starts, check to see if Office will update without a problem.
  • If the error appears, enable the services one after another and restart your computer after enabling each service to check the error.
