Where did you get Windows 7 Network Edition?

From post #1

I basically installed windows 7 network edition

I presume that you know what ever Windows 7 you use, a COA issued by Microsoft is needed to activate the system properly.

I wonder if the Enterprise version is involved, got it from his/her employer? If so the company holding the Volume License should have provided the Product Key necessary for installing.

There is an Upgrade path to a better version but not to a lesser version. The Enterprise version is usually equivalent to Ultimate.

It would be most important to know if the installed version is 64-bit or 32-bit, if changing from one to the other a clean install is necessary.
