I have an Acer tower, Aspire T180, with Vista home basic on. It has not been used since 2010, I have tried to activate it and I get 0x80072F8F.
I also have at the bottom of the screen, telling me it is not a real copy, it came with the tower and the Product Key is on the label on the side of the tower.
Do I need a new product number? How can I get my pc working?
