I installed Registry Backup and it appears to work properly. However, I am unable to open the program either with the desktop icon or *.exe file in order to modify settings. Would appreciate any suggestions to rectify this problem.
UPDATE: The program finally opened after a long delay of 20-30 minutes. Then about 10 minutes later an error message appeared:
"The program did'nt shut down properly. This may be due to a problem with the Volume Shadow Copy Service. ..."
Have switched to Fallback method and we'll see if that works.
