Unless you install it with the "add to path" option, deinstall it, and 
the reinstall without the "add to path" option. That is, assuming the 
install directory is the same every time.

Not that I think this is common, except in testing scenarios.

Except you still have the "last in wins" issue, and you have to make a 
decision on whether or not to delete the file.  But I agree that 
managing a single batch file is easier than dealing with the PATH 
variable, and has fewer side effects (finding DLL's, etc.).
