Sourcetree won't start anymore

[GreWull]

Suddenly Sourcetree doesn't work anymore. I can't open it and when I try to re-install it just show me a small blue logo with "sourcetree" and then nothing else.

I'm on windows 10

I tried to delete all the folder in Appdata\local but without success.

I get this in the .log

Hi Gregory, you can find the solution in this other Community thread, it's the answer proposed by Mike Corsaro:

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!

Best regards,

Ana
