Please see the Installation and Registration document, section 'Invalid Key Problems' (or the README.txt file). If you have re-installed windows, you will also need to re-install the latest combined VC++ redistributables.

You also posted for this issue on Discord. Please only use one support channel - posting here and on Discord is just more work for both of us.
