I ran the Direct X checker in System Information, and under the "Input Tab it reported registry errors and advised me to Re-install DirectX.

I downloaded the latest version from the MS site, and did the install. Still get a registry error reported as follows

Key 'HKCRCLSID{92187326-72B4-11d0-A1AC-0000F8026977}ProgID' is missing.

I've searched the KB for this error without success.

Any suggestions please
