Sourcetree crashes on startup
Asked by bgman:

I installed Sourcetree the other day on a new work computer and it was working fine, then after the weekend it appears to be crashing on startup. The splash window with the logo and title appears briefly, then it closes. Now after reinstalling it has the same behavior, splash window and then close. It does extract the files to AppData but doesn't open the installation wizard, and still doesn't open at all. I tried everything I can think of up to digging into the registry for sourcetree and atlassian leftovers, any fix I could find for KERNELBASE.dll and every other solution on this forum, but nothing I do seems to work.

Event viewer error:

body: I had the same problem. Sourcetree ran fine for months on Windows 10. Then I installed Open Office.

The error log showed .NET was crashing.

I uninstalled/reinstalled Sourcetree, I tried the fix using WMI, but those did not work.

When I uninstalled Open Office, it began working again.

body: Hi,

Please try to uninstall and then reinstall Sourectree.

1. Uninstall Sourcetree using the Windows Uninstall program.
2. Delete the folders/files below before proceeding to the next step:
   * Navigate to **C:\\Users\\\<UserName\>\\AppData\\Local** and delete all **Sourcetree** folders and files (if any)
   * Navigate to **C:\\Users\\\<UserName\>\\AppData\\Local\\Atlassian** and delete all **Sourcetree** folders and files (if any)
   * Navigate to **C:\\Users\\\<UserName\>\\AppData\\Roaming\\Atlassian** and delete all **Sourcetree** folders and files (if any)
   * Navigate to **C:\\Users\\\<UserName\>\\AppData\\Local\\SourceTree-Settings** and delete all **Sourcetree** folders and files (if any)

[Download Sourcetree for Windows](https://www.sourcetreeapp.com/) and install it

Let's see it works after this or not.   
if not then find the log file and send it here from below path.

**C:\\Users\\\<UserName\>\\AppData\\Local\\Atlassian\\Sourcetree\\sourcetree.log**

body: Hi, thanks for your reply.

I already deleted those folders several times after each uninstall during my attempts to make it work.

Downloaded the launcher again each time too, and the install does the exact same as trying to open it, briefly shows the Sourcetree blue window with the logo, then closes without ever displaying any window, it doesn't even show on the taskbar.

Installing does set the files on **AppData/Local/SourceTree** but neither opens the install wizard, creates an **Atlassian** folder in either Local or Roaming nor any visible logs on the install folder. It also doesn't create anything in **Atlassian** or **SourceTree-Settings**.

I also tried different, older versions of the install file and none work either. The **KERNELBASE.dll** error I get from the windows event viewer is the only thing I got.

body: It's strange. Could you please check that Sourcetree is provided all the access rights. It happens when corporate policies restrict Sourcetree to access these folders and then it does not create these and sourcetree try to access them on startup.   
Also please let us know which windows version is used and Sourcetree 3.4.8 is used now .Net framework 4.8 (upgraded into only this version of sourcetree).


author: bgman
body: I couldn't find anything that would suggest Sourcetree not having access rights. Asked our systems guys and they told me there's nothing that's being limited regarding instalations or folder access, since our team needs to install several different apps so they leave it up to our judgement.

My windows info is   
Windows 10 Pro 21H1  
Windows Feature Experience Pack 120.2212.4170.0

And I just made sure I had .NET framework 4.8 installed.

It's so weird because it did work fine when I first installed in this machine, but it just stopped from friday to next monday. I don't recall installing anything and nobody else uses this computer.

body: I have the same issue. Reinstalling didn't work for me either. I tried with a different user profile and got the same behavior.


author: Jose Rafael Castillo Pinero
body: I did could fix it repairing the WMI registry following the steps of following link: [Rebuilding the WMI Repository - Windows Forum - Spiceworks](https://community.spiceworks.com/how_to/21413-rebuilding-the-wmi-repository)

I founded it in community product question: [SourceTree crashes on launch (atlassian.com)](https://community.atlassian.com/t5/Sourcetree-questions/SourceTree-crashes-on-launch/qaq-p/614185)

I hope it help you too...

body: I'm having the exact issues that bgman is having. Splash screen appears for one second then disappears. Same .NET and KERNALBASE.dll errors in my event viewer. Bgman did you ever find a solution to your problem? Thank you
