This problem may occur if the Component-Based Servicing subsystem is corrupted in the Windows operating system. This corruption may result from incorrect permissions that are set by users or the administrator.

Click Start, click Run, type dcomcnfg.exe, and then click OK.
If you receive the User Account Control prompt, click OK.
