Hi Patrs63, welcome to the Seven Forums.

As you can not upgrade a 32 bit Windows to 64 bit, you of course need to do a fresh, clean install by booting the PC from the Windows Ultimate x64 DVD and later re-install all your software.

If you are using a valid install DVD there should be no such errors, Windows install media contains all files needed. If your install DVD is defect you should return it to the place where you bought it and request a replacement. If you have downloaded an ISO file from Microsoft or other official retaler, re-download it and burn to DVD using slowest possible speed and verification.

Where did you get Win7 Ultimate DVD and how is it being activated?

The error is almost always a bad installer.
