What is the cause of Microsoft error code 0x426-0x0?

After researching this particular problem, it turns out that Microsoft Office error code 0x426-0x0 can occur for several reasons. Here is a shortlist of possible culprits:

Click-to-Run service-disabled: One of the most common causes of this error code is a scenario where the main Microsoft Office Click-to-Run service is disabled in the Services screen. In this case, you can solve the problem by enabling the service and setting the status to “Automatic” on the “Services” screen.

Damaged Office installation: According to some affected users, this problem can also occur due to a corrupt Office installation. This can either be due to a corrupted file or a root in a registry entry. In this case, you will be able to fix the problem by using the Microsoft Office Auto Repair feature.

AVG TuneUp interferes: It turns out that some third-party utilities (most often AVG TuneUp) have been known to interfere with various Office applications (especially programs from the Office365 suite). In this case, removing the conflicting optimization program should solve the problem completely.

Conflicts between old Office installations: If your Windows installation currently contains multiple Office installations, you can expect conflicts between some program mitts, especially if they end up using common registry files. In this case, the only way to solve the problem is to uninstall the old Office installation.
