Product Key Won't Work

[CheapCharlie]

I had Office 2010 and Visio 2010 installed on my computer. My Windows installation failed and I had to re-install Vista on my other connected drive. I'm trying to re-install office and visio on the new drive and my visio product key won't work. I found the product keys on my old drive using Produkey. The office one worked but now I'm wondering if I wrote the number down wrong for Visio. I can't seem to find them again using Produkey. Is there any other way to find the old product key?

Thanks in advance

It was on the package if you bought a cd. If you registered it you will have to call Microsoft they are the only ones that can help be prepared to prove ownership. Forum rules prohibit anything further.
