Source Tree failing to install and run

I cannot login to SourceTree.  I've tried everything from deleting Atlassian sub-folders to finding older versions and re-installing them first.  I've tried logging in with Google and logging in with Atlassian password.  The one thing I haven't been able to try is to install SourceTree to a different directory since the installer doesn't give me an option to change it that I can see.  I don't need to revert back to .net framework 4.6.1 because I never went to 4.7 so that can't be the issue.  I've also tried downloading and running it from IE.

I am currently working with setup version number and each time I get to the login screen, it says "Sourcetree has stopped working".  I check the log file and it is completely empty. Clicking "Having trouble logging in?" also crashes the program.  I have not been able to get past this point.  I have read and tried countless threads on this issue to no avail.  I am just a single user at home so there are no funky admin/firewall things, and I turned off my virus checker.

Any other ideas that I'm missing?  Any help would be GREATLY appreciated.

Hi Rich, have you tried wiping SourceTree preferences already? If that doesn't help, you can try a clean install:

  1. Uninstall SourceTree (if it shows on the App&Features list)
  2. Backup then delete the directory below before proceeding with next step
    • Navigate to C:\Users\<UserName>\AppData\Local and delete SourceTree & SourceTree-Settings folder
    • Navigate to C:\Users\<UserName>\AppData\Local\Atlassian and delete all SourceTree Files/Folder.Download SourceTree and install it.
  3. Download SourceTree and install it.

Let us know if this worked for you!

Hi @Samirullah, can you check your logs and tell us if you find any errors? 

On Windows, the SourceTree log file is located at C:\Users\<username>\AppData\Local\Atlassian\SourceTree\sourcetree.log

Let us know!

Hi @Thomas_Hinze,that has been reported as a bug at The developers are looking into it, but we don't have a resolution yet. In the meantime, as a workaround, you can download the version 2.1, this is available from

I also recommend you to watch the ticket for further updates.

Let us know if you have any questions!



I  downloaded the 2.1 version same stupidity.  This just doesn't make sense.  Looking elsewhere

I'm encountering the same issues.  Why not remove the login from the install process completely, or build a better login solution?  Seems like this issue should have been solved by now.

I'm experincing the same issue.  I have tried the most recent version and a few others with the same result. I have also tried installing with admin rights. I get as far as here and it just keeps spinning.


I have noticed with Fiddler that it makes a call to POST with crsfToken and usersname in the body

Then there are 3 requests to OPTIONS each return with just the word "OK" in the body

Then nothing else happens.

Versions I've tried

SourceTreeSetup-, SourceTreeSetup-, SourceTreeSetup-


Got the same problems as above. Found SourceTree Log with the following content:

ERROR [2018-03-12 16:54:36,640] [1] [SourceTree.App] [.ctor] - finish EnsureSquirrelExecutionStubIsCopied

Maybe it helps.

Hi @Tom Knipphals, this seems to be a different issue. In your case you could try the solution proposed by Mike Corsaro in this Community post.

Let us know if that helped!


@Ana Retamal any news as to my comment? I am still unable to install, is mine a different issue as your previous suggestion of using an archived version does not work?

Hi @Adam, in previous cases the issue you described was caused by the settings in your browser. Sourcetree relies on Internet Explorer for authentication, please try the following:

  • Turn off compatibility mode in IE. To do that, open Internet Explorer, go to the Advanced options tab and click on Reset your Internet Explorer Settings
  • Check Delete personal settings
  • Change your Internet Explorer Security Zone Settings:
  1. Open IE, click on the gear
  2. Select "Internet Options"
  3. Select the "Security" tab
  4. Select "Custom Level" for Internet
  5. Find "Access data sources across domains" and select "Enable" (make note of what the setting currently is)
  6. Try logging into Sourcetree again

After logging in, follow steps 1-5, but reset the setting back to the previous option.

Kind regards,


Hi Ana,

Thanks , it works for me now 



I am having the same problem.  The installer only shows the splash screen at start and puts an icon on the desktop, but doesn't appear to run completely.  It doesn't give me any options either.  And the shortcut it installed doesn't run.  Help!

Btw. I did try what you've recommended.  Uninstalling, removing the AppData SourceTree folders, and reinstalling.  It doesn't help.

Hi Walt,

I had same issue then I removed Sourcetree and first installed .net framework then again installed Sourcetree and it works as expected.
