Error code 80070570 when trying to install Windows 7
Hi.
I bought Windows 7 CD and trying to upgrade from Vista x64-bit Ultimate Edition but after 15 % installation, it gives an error code 80070570.
I don't know what this error is about but every time I try to upgrade, I face the similar problem. Its frustrating me. Can someone give me direction as to what the possible problem could be.
