Sourcetree won't start

After clicking on it no GUI will open. It uses some CPU and Logs this.

Hi Mahdi, 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!

Regards,

Ana

Wow. Thanks for your fast replay. I do not have such a thing as in answer. And as I didn't think someone answers this fast, I uninstalled it, truing to reinstall and see if it works.

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

Thanks Ana, that did the job for me too, although as Mahdi Rafatjah stated, i didn't have that option either.  I added it manually.


After that i executed sourcetree again and it completed its installation/configuration.

 

btw, I am using windows 10 pro.

Same here. I couldn't start SourceTree (v.3.2.6) after I had restarted my PC, but adding that setting manually solved the problem.

Had the same problem with the exact same error. I had no setting like this in my config file. You have to add it manually, and it works.

 

Atlassian : Can you publish a fix for this ? It's a critical bug and I lost a lot of time trying to resolve this.

Hi @Francois BERTRAND, this issue was reported in our issue tracker at SRCTREEWIN-8046. Also, it's been asked in our Community multiple times, so the solution is also posted here publicly.

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 theupdate directly here: https://downloads.atlassian.com/software/sourcetree/windows/ga/SourceTreeSetup-2.3.5.0.exe

Hope that helps!

Ana
