SourceTree 2.3.1 Windows will not launch

StackOfRules

A fresh install on Windows 10 (never installed before), and it will not launch. Tried all of the remedies in other threads to no avail. That includes:

1) Deleting the AppData\Local\Atlassian\SoureTree.exe_Url... directory
2) De-intalling and then...
3) Deleting the AppData\Local\Atlassian and AppData\Local\SourceTree directories

The sourcetree log shows:

ERROR [2017-09-21 12:29:08,609] [1] [SourceTree.App] [.ctor] - finish EnsureSquirrelExecutionStubIsCopied

Any suggestions?

I tried this on a VM, and found that the install is never fully completing on the development platform. I have no idea why. It launches, shows the splash screen and then stops. The desktop icon is created, but the configuration dialog never appears.

Cleaning the windows temp dirs worked for me. Same issue before.

StackOfRules

Tried that - no effect. Same results.

I even tried installing on a stock VM (where it succeeded), connecting to a repository, then copying the files to the problem system. It still generated the same error in the logs.

Checked the OS (no problems found), and tried other clients (i.e., GitKraken - all worked), but SourceTree has some issue that I can't pin down.

Have you tried navigating to the config file location (C:\Users\{USERNAME}\AppData\Local\Atlassian\SourceTree.exe_{RANDOM_GUID}\2.3.1.0\user.config) and then including the following line

<setting name="AutomaticallyCleanUpDictionaryFiles" serializeAs="String"> 
     <value>True</value> 
</setting>

I was having the same problem as the OP, including the same stack trace and symptoms, and this answer solved my issues.

Thanks Austin!

StackOfRules

You da man!!! Yes, adding that to the user.config worked! The installer kicked off on the next launch. Thank you!

This worked for me as well.

Renamed SourceTree, SourceTree-Settings and tmpAtlassian to tmpSourceTree, tmpSourceTree-Settings and tmpAtlassian on C:\Users\{user}\AppData\Local .
In my case, worked.

I had the same issue - Austin Mason's solution above worked for me to fix this as well.

We have a fix for this being tested at the moment.

Is this fix available yet? Sourcetree just stopped working one day. I uninstalled it and tried to re-install, but the installer just seems to stop after a while. Icon is placed in start window, but it can't be started.

Hi everyone! As an update for this question, we have just started the progressive rollout of Sourcetree v2.3.5.0 which includes a fix for this issue. You should be prompted to upgrade sometime over the next 14 days or, alternatively, you can download the update directly from https://downloads.atlassian.com/software/sourcetree/windows/ga/SourceTreeSetup-2.3.5.0.exe
