ANOTHER USER POSTED THIS:
I was able to resolve Error 42016 by downloading and installing the latest version of the program from my downloads. (use your license code for download access if you purchased a cd) When you receive message that a previous version is already installed, choose Remove to uninstall. Once uninstalled, right click on the freshly downloaded program and choose Run as administrator. Proceed with installation.
When you launch the program, if the error 42016 message persists, click Try Again. When the error message persists a second time, click Don't Try Again. For me, the update then began to download and was successfully installed. Upon relaunch, the error no longer appeared.
