Memorex scanners were never properly supported in Windows XP so Vista is totally out for them.

Go to site http://support.visioneer.com/products/home/EOL/Memorex/
Download/save application file 6142. Check file properties, under compatibility select "run this program..." and choose Windows XP(Service Pack 2).
Then run the program.
This worked for me with Windows Vista Home Basic.
