But, Dimension Pro works.
 
Had to reinstall with new system drive, but have my samples (all the Dim and Rapture available) on a second drive.  I have the registry entry point to both of them just as I did before the drive change.
 
Dimension Pro samples are in F:\Dimension Samples  (and in that directory is the Multisamples directory).
Rapture Pro samples are in F:\Rapture Samples (and in the directory is the Multisamples directory).
 
All this used to work, and now it doesn't.  Not one patch works, with all saying "Program Load Failed".   Very frustrating.
 
Any ideas?

FIXED.
 
I was entering the directory in the Rapture Pro 2.0 line under "Rap Multisamples", thinking it was an abbreviation for Rapture Pro.
Up above, at the Cakewalk Music Software sublevel is where it belonged.  Using "Log" gave me the insight after doing a search on "Multisamples" in the registry and finding the other line.
 
Best to all.
