This worked for me,
Cause This error is generated by Windows Update KB929427 which was
distributed to Vista customers on 1.30.2007.
Customers not running Easy Media Creator 9, or other Vista non-compatible
software by Roxio, may experience this issue as well.
Resolution Roxio is currently working on a resolution to this issue. The
error, while annoying, will not effect Easy Media Creator 9's functionality.
However, if you wish to eliminate the error, the only work around at this
time is to temporarily remove the update.
Please read the Microsoft Knowledge Base article The Windows Vista
Application Compatibility Update before continuing. Removing this update may
effect other applications on your computer. If you wish to reinstall the
update at any time, the Microsoft Knowledge Base article offers a link to
re-download it.
Also, be sure that you are running a Vista compatible version of Roxio
software as listed in the article Windows Vista Support for Roxio products.
If you are unsure of what version of the software you have, you can find out
by launching the software and choosing About ... from the Help menu.
To remove the update:
1.. Go to Start -> Control Panel -> Under Programs, click Uninstall a
program.
2.. On the left of the Programs and Features window, click View installed
updates.
3.. After the Installed Updates window loads, scroll down to the Microsoft
Windows payne.
4.. Right-click Update for Microsoft Windows (KB929427) and select
Uninstall.
5.. Rather than restart your system, shut it down completely and then
reboot. The error should be eliminated.
