Contrary to what the Amazon product page says, this game is not Windows Vista compatible (and therefore not Windows 7 compatible). Amazon has a license from Knowledge Adventure (aka Jumpstart) to manufacture and sell these CDs. They are printing the systems requirements incorrectly on the CD insert as well on the web page. After installing the game and finding it doesn't work, I called Knowledge Adventure tech support. They stated that anything that was Windows 2000 compatible will not run on Windows Vista or Windows 7, and that they have had repeated problems with Amazon selling these items inaccurately to the point where they're considering revoking the manufacturing agreement. Tech support did the best they could, walking me through everything to try in the hopes of tricking the system into playing the game, but nothing worked. They said they have updated their Math Blaster software to work on the current versions of Windows and recommend that as an alternative product.
