When i start the program FME Workbench version 2021.1.2 and 2021.2.6, the system start up as expected.

But when i try to start FME Workbench 2022.2.2, 2022.2.4, 2022.2.5 or FME Form 2023.0 the start window appears. But when it comes to "Initzialising main window" the system craches every time whith a loggmessage in the Windows Event Viewer: (Sorry about the swedish language in logg)

It locks like there is som problem with the ucrtbase.dll.

I've been testing many different versions of FME and reinstalled them several times and even done some repair installations on some of them but nothing works. Is ther anybody here who know how to fix this problem?

After several attempts and hours of testing, I have determined that this error is tied to the user account of the AD login. If one of my colleagues logs into my computer and starts FME 2023, it works fine. But I'm still having problems.

Solved! I renamed the FME-folder created by the installation in MyDocuments. Because we have Microsoft 365 this folder is syncronized between all units that I log in to. So therefore the problem folowed aswell.
