CorelCAD 2020 Windows Ctrl-C (copy) funciton needs to install, can't find .msi file to install from.

When I purchased CorelCAD, I was provided with an .exe file to install from. Installation went well, been using CAD without issue...

When trying to use Ctrl-C to copy objects from one drawing to another, CAD tries to find the install .msi file but can't. No copying for me. What can I do?
