I have this installed successfully in the D257 of Acer. I visited the Microsoft site and downloaded the program on a USB Home premium windows 7 (32-bit). Later, I had problems with the computer and decided to windows 7 from re - stall.
Then I had the upgrade key sent to me by e-mail, what's left. Last year I used widows any time upgrade to install 'windows 7 Home premium upgrade,' which has been installed via the internet by a Microsoft technician. It came pre-installed with 'windows 7 starter' I don't have a disc of recovery etc for this program.
