I have downloaded build 3633 but when I attempted to uninstall build 2302 it is not in the Add/Remove programs list but it is on my system and works. I tried using Windows Installation Cleanup utility and Acronis didn't appear on that list either. Any suggestions would be appreciated. I'm assuming that a manual uninstall will be required involving deleting a number of registry keys, etc. which I'd rather not do if anyone has a more elegant solution. Thanks!
