On your Hardrive can you create another partion (take some space from "C" drive,say about 20gigs and then call it Whatever and label it...
You can use an external Partiton program on the net that is free,or use windows 7 version for creating a partition..
Uninstall FDC using control panel/program features...
Reinstall FDC into your new partition..
Hope this is alot clearer...
