Thank you for the great suggestion.
Would you mind elaborating on how exactly you resigned the dll?
I opened the dll with Reflector & the reflexil addin and the edit to SQLite.Designer.dll to point to "9.0.0.0" was easy enough.
But I'm unfamiliar with resigning and can't seem to figure out how to "resign" the file properly using reflexil's save options or Sn.exe from the command line.
I tried using the patched and unsigned dll with the installer but it threw an error saying that it required a signed dll.
