The activation Servers for up to Photoshop CS2 have been taken offline.
v6 didn't require activation. I would double-check your s/n in your "My Adobe".

Ah, I didn’t know that.
Even if s/n would work you may have a lot of problems getting it to work on Win7. Save youself a lot of grief and just download CS2. You are qualified I believe as you had purchased PS6. CS2 free download is on the web someplace.
If you have 6.0.1 installed on another PC, just copy the Photoshop folder to your Windows 7 PC. It will work fine providing your hard drive is not over 1 TB.
You will able to start PS 6 normally in Windows 7.
