SourceTree crashes on startup
When attempting to start SourceTree, the following dialog is displayed with the message "SourceTree has stopped working", and the application does not start:
- Open the Event Viewer in Windows right after the crash
- Go to Windows Logs >> Application
- There should be two Error entries.
One of them has as Source: .NET Runtime
Application: SourceTree.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.Configuration.ConfigurationErrorsException Stack: at System.Configuration.ConfigurationSchemaErrors.ThrowIfErrors(Boolean) at System.Configuration.BaseConfigurationRecord.ThrowIfParseErrors(System.Configuration.ConfigurationSchemaErrors) at System.Configuration.Configuration..ctor(System.String, System.Type, System.Object) at System.Configuration.ClientConfigurationHost.OpenExeConfiguration(System.Configuration.ConfigurationFileMap, Boolean, System.Configuration.ConfigurationUserLevel, System.String) at System.Configuration.ConfigurationManager.OpenExeConfigurationImpl(System.Configuration.ConfigurationFileMap, Boolean, System.Configuration.ConfigurationUserLevel, System.String, Boolean) at SourceTree.App.SetStartupJIT() at SourceTree.App..ctor() at SourceTree.App.Main()
The second one has as Source: Application Error

The most likely reason for this error is that the user.config file for SourceTree has been corrupted.
You can confirm this by locating the file in this location:
If this is the cause, when you open the file, it will be full of <NULL> values.
If the user.config file is indeed corrupted, you may delete it.
It will be regenerated the next time you start SourceTree, and the application should start normally.
