start up error - "The procedure entry point not found" & will not acknowledge registration

I am having 2 problems (I don't know if they are related)

  1. The program does not recognize that I have registered.   (Tried multiple times to register and uninstalled then reinstalled with no change)
  2. Every time I launch the program, it gives me a pop-up with the following error:
  • The procedure entry point
  • ?fromWCharArray@QString@@SA?AV1@PEB_WH@Z could not be located in the dynamic link library Qt5Core.dll.

Has anyone come across this before or have a suggestion?
