	Sure -- since Windows uses a Registry entry to identify how to execute
stuff... Rename the directory used in the installer, and you need to go
into the registry and modify all references to the original directory to
match the new location. All the shortcuts also would have the original
location embedded into them. Oh, and the PATH might be affected.

	This would happen with 99% of the software installed on a Windows
system. The remaining 1% may not use the registry -- but would maybe still
need changes in the PATH environment variable.

	Hmmm... Time to edit MY system's PATH... I don't do enough with PIC
processors to have mplabc18 at the front of the search order; same with
SPARK...
