I had to reformat my computer and so I reinstalled Impulse with the latest download-able version.
The first Stardock program I installed was "Tweak Vista". When I clicked on the Tweak Vista icon later in my start menu it said that the program couldn't be found.
I went into my program files and discovered that the .exe file was incorrectly labeled "Tweak7" - and this is what was causing the path to come up empty. I renamed it and it works fine now, but I thought someone might want to look into fixing this before it causes problems.
