I have 10.3 installed in windows 8. All was perfect with the trial key.

I bought the key and got my e-mail. Now I'm going to  the desktop, select license, change license  and enter the key. If I get it wrong all is good and I get a error.

If I get it right.... I get a dump.  I've tried uninstall, reboot, reboot, reinstall with the same results .

The event log shows:
