What worked for me
I tried the previous suggestion it did not work.
But what did work was this:
This can also be an error of the Update Manager unsuccessfully attempting to update itself. To update, remove this program using the
Add/Remove Programs control panel. It will be called either "Roxio Update Manager" or "Sonic Update Manager". Then download the latest version
here and install.
If you decide to permanently remove the Update Manager, it will not affect the performance of any Sonic or Roxio software currently installed on the system.
Mine worked on the first try.
If you still have a problem try this:
If Update Manager fails to uninstall, corruption has occurred that prevents removal. You will have to manually remove Update Manager: Download and install Microsoft Cleanup Utility located
here. Run the application and select Sonic (or Roxio) Update Manager, and select
Remove.
- Go to My Computer --> C:\\Program Files\Sonic. If there is a folder named Update Manager, right click on it and select delete.
- Browse to C:\Documents and Settings\<--user name-->\Application Data\Sonic and delete the "Update Manager" folder.
Here is the link tho the sonic site with this and other tips for this fix:
