I'm upgrading from TI Home 10 which was running on XP Pro
Upgraded my PC to Windows 7 64-bit.
Just paid $29 and downloaded the TIH 2012 application and the product key
Install asks for new (upgrade) product key and and the old product key
Entered the TIH 2012 upgrade product key that was just sent
Entered the old TIH 10 product key (note that it is much shorter then new key)
The "Next" button remains greyed out - I can't continue install.
BTW, if it makes any difference, the v10 version key is an update key from v6. I also tried the v6 key, but to no avail.
