Multiple users unable to open SourceTree at the same time in a VM

[Victor Ramirez]

I have a VM with Windows server 2019. In this server, I have multiple users with individual SourceTree installations but we are facing a problem where only one user is able to execute SourceTree at the time. Any other users who attempt to load the software while another user has it open will get it to crash. We have tried to reinstall it multiple times following articles found in the community with no luck.

The Application error log:

[Victor Ramirez · Accepted solution]

This issue was resolved following these steps:

1. Uninstall SourceTree from the conflicting sessions
2. Clear all SourceTree files from the conflicting sessions
3. Reboot the VM
4. Install SourceTree for each account one by one
5. Reboot the VM

Best!
