It does look like a problem restricted to Vista users. I've had had users contact me over several different giveaways who cannot activate on Vista - despite being administrator and running activate and seeing a "successful activation" message.

The registration data just isn't on their PC...

Makes it difficult for me to help them - I've got no plans to go anywhere near Vista until SP1 + 6 months (at the earliest). (Maybe not at all if the DX10 conversions for XP are successful).

Hmm...maybe it's a Vista problem? It works perfectly here on XP. (Honestly, I really don't believe in jumping to a new operating system until say...service pack 1 at least - too many incompatibilities).

I have same problem. Running Vista and I am the administrator. Product states it works fine, but asks for email and reg code.

Please give more specific directions. Both of us have stated that we are activating as administrators and it still is not working. Thanks for your help!

You need to run Activate.exe as Administrator.

The Same is happening to me! :(

This program states that the activation took place but the program asks for my e-mail address and registration number. It also states that I have 30 days left. I am using Vista and am the administrator. I activated properly and then set up the program per the directions. Please help!!
