I purchased the upgrade and started the installation of the upgrade from ver. 9. It asks for the new serial number then the old serial number. It then states that it is installing the program. It get almost all the way done and the progress bar goes back to the left. It says that "The installer was interrupted before Acronis Disk Director Suite could be removed. You need to restart the installer to try again." I've restarted over a dozen times. It won't install. I even tried in Safe Mode. It gives me error #1601. Don't you just hate buying software that doesn't work. Anybody having any suggestions? And, no, this isn't a 64 bit PC. It's a 2 year old machine running Windows 2000 Pro with SP4. Version 9 of this program worked fine. Guess I shouldn't have upgraded. Thanks. Keith P.S. I also purchased the upgrade to True Image and it had no problem upgrading.
