Do not remember when this my have started but I have brought a few hardware items latley & found out that I cannot install the software that came with them. Brought a new DVD drive & a Iogear for my daughters Bluetooth. I could not install either software on my computer but they will install on her laptop.I downloaded the driver file for the Iogear off the internet & it would still not load up, So I decided to see if something old would load up, so I deleted a game that was on my computer and tried to re-install it again and it also will not install now. So has anyone ever heard of a computer acting like this and if so what can cause it. thanks
