SourceTree Stopped Working on Windows 10

[Mark Wright]

I have searched the community for a similar issue I am having but did not find any like the problem I am having.

I am using Windows 10

My SorceTree stopped working. When I run it SourceTree nothing happens (no error message, no screen, nothing). I have tried reinstalling SourceTree by first uninstalling the program. Then deleting the Users\<user>\AppData\Local\SourceTree folder and the Users\<user>\AppData\Local\Atlassian\SourceTree folders. When I run the install I do not see any screens but notice it does put a shortcut on my desktop and recreates the folders in the \Users\<user>\AppData\Local folder and the \Users\<user\AppData\Local\Atlassian folders. When I try to run SourceTree after the install nothing happens

Hi there is a fix on its way, but for now there is a workaround described here:

https://jira.atlassian.com/browse/SRCTREEWIN-7898

This solved my issue...thanks

Same issue here. Win 10 install was working fine when I shut down yesterday and fails to launch this morning. Uninstall, but then current installer won't run (well, it creates some files but nothing ever shows up and what it creates also won't run).

This workaround didn't help.

I tired a few recent versions, and finally 2.1.10.0 will install and run.

Any idea what caused this?

Which version of Sourcetree are you using?

Additional info might help us to solve the issue. Could you check the log of Sourcetree? 

Here is the link how to find sourcetree log file:

I'm using SourceTree version 2.3.1.0

Here is the contents of the log for the day I tried to install it on.

I've got the same problem today. This is BLOCKING me from using the software.

I've got the same problem with this edition on Windows 10. This BLOCKING me from using source tree.

I'm getting the same issue as Mark, with the same log.

I'm running Windows 10 Pro. Trying to reinstall v2.3.1.0.

Tried uninstalling, cleaning registry, reinstalling, rebooting several times. But when it comes the new install, it just fails.

I've seen below that there is a fix incoming, but I just wanted to add to this thread.

Thanks

I'm in the same boat with the same exception.  I had to go back to 2.1.2.5 to get a working version.

Same issue for me. SourceTree stopped working on Windows 10. Currently using other git software that actually loads along with command line to do my daily work.

[viren_karmaln]

I have faced the same issue applying the above solution but still SourceTree not working 

[John Winters]

Sourcetree not working.. we stopped usin it.  We are down to Sublime or git now.
