Have you tried scanreg /restore to restore a previous version of your registry? The info is stored in the registry,this link will show you where:

Thanks for the info vinnyd79.  The UNINSTALL key in the registry is indeed empty.  Do you know of any utilities that can display the registry contents of the registry backup files?

Although the reverse of what you need, may help you in terms of the key and perhaps searching your system in case saved.

Have you tried scanreg /restore? You could try backing up your current registry,then restore a previous version and see if the entries are there.if they are use the file menu in regedit to export the key to a .reg file.Then you could restore the registry you backed up and run the .reg file to add the entries back in.

Here is more info on scanreg

Thanks vinnyd79 for putting me on the right track.  With a lot of trial restores and fiddling (windows only keeps and shows 5 registry backups) and help from my Nortons Recycle Bin, I managed to recover a registry backup that did the trick.  Thanks to everyone for their input.
