unable to locate executable

I've been using Gallery remote for more than a year now. Today I tried to open it, but all I get is a "launchAnywhere error" that says "unable to locate executable". I assume that some .dll or something is missing, I haven't changed anything recently. So, I uninstalled gallery remote and then reinstalled. I still get the same error. Does anyone have a suggestion for what I need to do to fix it?
