Trouble Installing OS

Aug 31, 2010 4:31AM PDT

Hey guys,

So I just finished building my first computer. I am trying to install windows 7 ultimate 64 bit as the first OS and it keeps saying the cd key is invalid. I am a student currently and on the CD it says 64-bit x64 upgrade: PRE EXISTING OS LICENSE REQUIRED. I am wondering if this is the reason it will not work. Since this is planned to be my first OS, does it make a difference or do I need to go and buy and old OS just to install that first? Please help!!! thanks!

Tell the forum what OS CD and License you are using for the basis or requirement of this upgrade version.

Yes.

Since that's all you have you can't install this OS as you don't have any qualifying OS, CD and License to qualify this install.

Glad we sorted this out so fast.
