Note: This is generally caused due to permission restrictions to Network Service Account. You can see Event Log (type eventvwr.msc in Run Menu) in System Part and you will find error like: "The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {FF76CB60-2E68-101B-B02E-04021C009402} to the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20). This security permission can be modified using the Component Services administrative tool."
