SystemWorksPro 2003 unable to fix error message :missing or invalid key

When I run SystemWorks Pro 2003, it detects this error but is unable to fix it.

 

missing or invalid key: "CLSID{1171A62F-05D2-11D1-83FC-00A0C9089C5A}\InprocServer32"

 

My PC has Windows XP home service pack 2 installed.  I've tried google and couldn't find any other forums that can help with the problem. I will be getting the latest SystemWorks and hope that it might fix the problem.  Any assistance much appreciated. Thanks.
