PC utilities forum: Uninstalling Acronis True Image 2011 disables Windows backup

You have to go to the registry and go to [HKEY_CLASSES_ROOT\CLSID\{B98A2BEA-7D42-4558-8BD1-832F41BAC6FD}\Instance\InitPropertyBag]. The problem is that Acronis took ownership of this location keeping you from updating the key. Follow the steps below and it will allow you to make the required changes.( taking ownership ) I went to that key and successfully took ownership...
1. Click on key and select properties.
2. click on "advanced"
3. select "owner tab"
4. change "System" or "Trusted Installer" to yourself "Name Administrator Blah Blah" Click Apply... OK
5 Back at original "permissions screen"... click on the name you just selected and "tick off the check box" to give yourself "full control" Sometimes it even appears "Grayed out"... you can still check it off.
6.That should do the trick
7. Now change the ResourceDLL to "%SystemRoot%\System32\sdcpl.dll"
8. Finally change the ResourceID to "14" Hex.

This is only why to fix this, unless you created a restore point before installing Acronis. When you uninstalled Acronis, Acronis did not set the ResourceDLL to "%SystemRoot%\System32\sdcpl.dll" or the ResourceID to "14" Hex. It was left point to the Acronis program.
