Windows 7 Home Premium activation won't work

[Qusus]

I have an older Acer 1410 that I recently replaced the HDD on.

On the Microsoft sticker, the product version reads:

"Windows 7 Home Prem OA Acer Group"

Underneath that is the product key.

I know I had a 64bit version of Windows 7 installed, so I downloaded an ISO of Windows 7 Home Premium from digital river and installed it on my computer. (The laptop did not come with it's own installation disc)

However, when I try to activate the product using the product key, I am told that the product key is not correct. I recall being able to call Microsoft to activate over the telephone in the past, but it appears this option is not available any more?

What can I do to activate my copy of Windows 7 with the product key I have?

Check the letters carefully....Sometimes a 8 looks like a B, 0 looks like an O etc. etc.

I had the same hassle when re-installing Windows 7 on one of my past laptops and it took me 8-9 tires with revising what I wrote down so many times until I finally got it and another option you could probably do is call the manufacturer and order recovery disks for your particular model that is what I had to do to fix my current laptop
