Hello All, I seem to be having the same problem as some of the other people on this board and i can't seem to resolve the issue.
I have an A31p and everytime i run the software installer it gives me an invalid machine type error.
I read some previous posts and you had asked to check the system information and it seems mine has the machine type missing.(see below)
