Sourcetree windows erroring on open

Whenever I attempt to open sourcetree on windows, I get errors that cause the application to not open. I have attempted reinstalling, restarting windows, clearing the Atlassian folder in AppData, to no avail.

 

```

Hi Zach, have you tried the solution proposed in this other Community thread?:

Please navigate to the config file location (C:\Users\{USERNAME}\AppData\Local\Atlassian\SourceTree.exe_{RANDOM_GUID}\2.3.1.0\user.config) and find the following line:

<setting name="AutomaticallyCleanUpDictionaryFiles" serializeAs="String">

   <value>True</value>

</setting>

Make sure that value is set to True

Let us know if it worked for you!

Cheers,

Ana
