I think that the application doesn't look for the right localized name of the program files paths. Do you use a non-english (local) version of Windows ?
If so, create a path Program Files and move the program folder iAltWeather (including of all files) to that new location.
Try to run the application from there.
Good luck, keep me posted

I'm using Dutty's 3.4 WWE
so the problem about localized or something is not possible I presume
