SourceTree crashes on startup and install


SourceTree crashes on startup and when I try to reinstall it.

After uninstall I removed appdata/local/atlassian and appdata/local/sourcetree folders as I read this helped someone but still can not launch the installer. All I see on startup is the message written lower. 

Does anyone know is there a way to make SourceTree work?


Here's the message

Hi! Can you try a clean install? The steps are as follows:

  1. Wipe SourceTree preferences
  2. Uninstall SourceTree (if it shows on the App&Features list)
  3. 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.
  4. Download SourceTree and install it. 

Also, let us know which Windows version are you using and which version of SourceTree are you trying to install. 




I've done everything you wrote as cleaning ST preferences folders and uninstalling it.

But it crashes with the same mistake when I try to run the installer.

I have Win7 64bit. Probably it's system, not bitbucket problem.

You aren't alone @Jar_L, I've been experiencing the same problem for months. They recommended a complete re-install of .NET, which I did, but it didn't help at all. Unfortunately, it seems that they only respond to the initial post, when I tried to get further help I got no replies.

Please let me know if you've found a way around this.

I also have the same issue and have had to revert to version 1.7. I have removed all relevant files and registry entries and the installer still crashes every time it is run with an entry in the log file saying "Failed to Start" with no reason which is not very helpful.

If anyone does find out what the issue is or when this issue has been fixed please let me know.

Deleting .\AppData\Local\Atlassian worked for me.

Has anyone else seen this associated with odd directory issues? I was doing some final debugging/verification of a Python module with SourceTree open when SourceTree crashed, the module directory was empty. Afterwards I couldn't get Windows to clear the directory.

yep, that worked for me too
