rik and Piper:

Sorry,

Cannot reinstall. Have too many legacy programs without the means of reinstalation.

In my next computer build, will place all programs on a separate drive from the drive my OS is installed on.

For now, can you fellows suggest another solution path, or am I at a dead end?

Would like to try to re-install SP4, but how do I do this?

Any chance that replacing the registry key would work? If so, can you describe procedure?

Thanks, Peter
