Hi martofbristol,
What is the version of operating system installed on your computer?
- If you are using Windows 7, you may run Windows Update troubleshooter that would help us diagnose the issue better.
Open the Windows Update troubleshooter:

- If you are using Windows Vista, you reset Windows Update components and check if you still get the error message.
Click on the Fix it button in the article below to do that automatically or you may do it manually as well. For more information refer to the article below:
