Exit Code 1603: A newer version of this application is already installed on this computer

I’m seeing more issues. After I run the installer of V9.1
It run successfully for some machines, but the old version is not removed and both versions are shown in the Program List, however the current version is directed to the old version.

This is what I can see on the log
