Warning appears after installing GEMPACK programs

Just after installing GEMPACK programs, a warning message similar to that below may appear:

PCA warning


We believe that the warning is needless and that you should click "This program installed correctly" as indicated above.

Cause: the install system used to build this GEMPACK install package is older than your version of Windows, and is not compliant with all recent Windows "requirements". The message seems more likely to appear if you installed directly from a CD/DVD.
