Windows 7: slmgr "invalid combination of command parameters"

I purchased the Windows 7 Ultimate upgrade, in order to install onto a new HD.  I was previously using Windows XP, but found this article in order to perform a clean install on the new drive and then activate Win 7:

http://www.mydigitallife.info/clean-install-windows-7-with-upgrade-media-and-product-key-on-formatted-or-empty-blank-hard-drive/

Within two of the workarounds presented in the article, it mentions running - from the command prompt - 'slmgr'.  I have run this command a number of times (run as an administrator), but every time, I get the "Invalid combination of command parameters" dialog boxes.

I have tried every combination I can think of - running slmgr with and without the '.vbs' extension, using '-' before the parameter, using '/' before the parameter, etc.

Any and all help would be greatly appreciated!

If you have done a keyless clean install...then boot to desktop...launch the windows 7 setup..click on the upgrade option...this time enter the product key and complete the setup...your copy will be activated for sure.

This might be a stupid question, but is there an issue in doing what you suggested due to the fact that I've already installed the majority of my applications, and have moved my files over?
