Installer crashes when trying to install tweak

[csamples22]

The installer seems to run perfectly fine then I get this error code:
Unhandled Exception: System.ArgumentOutOfRangeException: StartIndex cannot be less than zero.
Parameter name: startIndex
at System.String.Substring(Int32 startIndex, Int32 length)
at System.String.Substring(Int32 startIndex)
at Unjailbreaker.Program.<>c__DisplayClass18_0.

Delete the settings file and try again
