Windows 10, sourcetree 2.3.5, does not start

[Ryan Martin]

Sourcetree starts up for about 5 seconds in task manager, then exits silently. Have tried uninstalling, reinstalling including clearing the AppData folders.  Also tried installing an older version but that too force closes. Note: this issue is related to this specific machine, 2.3.5 is working on another machine of mine. 

Thanks. 

Here is the log:

Since you only see this on a specific machine, you may want to checkout this and see if it helps:

Thanks for the response, the link contained in there got me to the right area to get it working again. 

My final solution:

open cmd with admin rights

browse to C:\Windows\Microsoft.NET\Framework64\v4.0.30319\WPF

and run the command:
regsvr32 PenIMC_v0400.dll

Source tree now loads after installation
