This issue occurs both when upgrading via VulnDetect and Intune. In some cases, it even breaks the existing installation during rollback of the failed update.

As a result, we pulled the update before releasing it to customers.

Once Google has fixed the Enterprise "ready" MSI installer, we will update the package and make it available after thorough testing.

Please "upvote" the following post by Mikhail Gurin if you are affected by this and have a Google account. Hopefully, this will help make Google prioritize the fix: https://support.google.com/chrome/thread/311347547

For reference, we use the following installers:

https://dl.google.com/tag/s/dl/chrome/install/googlechromestandaloneenterprise.msi
https://dl.google.com/tag/s/dl/chrome/install/googlechromestandaloneenterprise64.msi

We also tested the EXE-based installers for offline deployment but found that these are incompatible with MSI-based installations.

It should be noted that the MSI works if launched interactively as a regular user who can approve the UAC prompt.
