On a non-Vista VersionSaver can run from any disc or directory on your computer. It is not fussy about where it is installed. Normally you don;t need to change the default installation location unless you are running low on disc space for that disc.
On a computer running Windows Vista, VersionSaver cannot be installed under the usual ProgramFiles directory on drive C. A different default directory name will be supplied. This is because of some security restrictions in Windows Vista.
After installation you need to complete a few, simple Setup Tasks, then VersionSaver is ready for use.
