I'm trying to install VS2010 on my new Windows 8 machine. This is an install from an MSDN subscription and it installed fine on my Windows 7 machine. But when I try on the new machine, I have to accept the EULA, and then it shows a messages that says:

You have entered an invalid product key for this product. The 25 character product key may be found on the media case or obtained online at: [some Microsoft page]

But this is really weird because there's no place to enter the product key, and it never asked for a key on Windows 7, which installed and worked fine. So I think it may be a Windows 8 thing.

Anyone know what's going on here?

Here is a solution I found online for your problem:

  2. Open this setup.sdb file in Notepad like program.
  3. Find the tag [Product Key] BD9TPWJD9XBWX4KQPWVY4GW9G
  4. Replace this product key by new key either from any source or from


People say it helped.
Good Luck

This worked to let me enter my product code, and then I was able to enter the correct code and install. Thanks! – Joshua Frank Jan 6 '13 at 22:26
