What are OSMMUI.msi Error Messages?

General OSMMUI.msi Runtime Errors

OSMMUI.msi file errors often occur during the install phase of Office, but can also occur while the program is running. These types MSI errors are also known as “runtime errors” because they occur while Office is running. Here are some of the most common OSMMUI.msi runtime errors:

Runtime Error!

Program: C:\MSOCache\All Users\{90150000-00E1-0409-0000-0000000FF1CE}-C\OSMMUI.msi

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Most MSI errors are due to missing or corrupt files. Your OSMMUI.msi file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Office), or deleted by a malware infection. Furthermore, OSMMUI.msi file corruption could be caused from a power outage when loading Office, system crash while loading or saving OSMMUI.msi, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve OSMMUI.msi problems.

Download OSMMUI.msi Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying OSMMUI.msi to your appropriate Windows system directory. Microsoft typically does not release Office MSI files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing OSMMUI.msi and all other MSI files for Office. An incorrectly installed MSI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
