Some information for NT4 users.

I downloaded and installed the online version of X3D5, entered the unlock code and off we go. I install as administrator but as usual the code has to be entered separately for each user on the PC.

A few days later the CD arrives, so to keep everything neat and tidy I uninstall the downloaded version and reinstall from CD with all the extra goodies. Enter the CD code and off we go again. Except that every time I start up X3D5 I'm prompted for the serial number.

To cut a long story short I reinstalled the downloaded version over the CD version (both 5.02) and everything is fine.

Possibly something to do with different installation routines?

I seem to remember similar problems with XaraX but that was solved by the time the CD appeared.
