Hi, my windows 365 apps do not function. I spent already more than 2 hours with the support team and they came to the conclusion that something on the security settings of my computer are interferring with the correct installation and applications of the microsoft 365 apps.

Microsoft 365 Standard funktioniert nicht - TrackingID#[Moderator's note: PII removed]

"The affected device is currently unable to launch Microsoft 365/Office applications as well as several other applications.

When attempting to start an Office application, an error is displayed indicating that OfficeClickToRun.exe cannot be found at the expected path:

C:\Program Files\Common Files\Microsoft Shared\ClickToRun\OfficeClickToRun.exe

The issue is not limited to a specific Office application. The user reports that multiple applications on the device cannot be launched, indicating a broader system-level application launch issue."

It would be really great if you can help me.

Kind regards

Alexander

    Hello Alexander Böttner,

    Since several unrelated applications are also failing, the issue may involve the Windows installation or the current user profile rather than Microsoft 365 alone.

    As a next steps, test a new Windows profile first, then proceed with an in-place repair if the problem continues.

    Please create a new local administrator account and test whether Office and the other affected applications open normally there: Create a local user or administrator account in Windows.

    If the affected applications work normally in the new account, the original Windows profile may be corrupted. You can then migrate your personal files to the new profile by following Microsoft’s guidance: Fix a corrupted user profile

    If the same issue also occurs in the new account, try repairing Windows through Windows Update. This reinstalls the current version of Windows and repairs system files and components while preserving your applications, personal files, and settings. If Fix problems using Windows Update is unavailable, use the Windows installation-media method instead and select Keep personal files and apps.

    Let me know how it goes!
