Hi, I bought a Sony Vaio (touchscreen, all in one) a couple of years ago and it came with windows 7 64 bit installed (along with a lot of rubbish programs). I decided to download windows 8 and bought an upgrade but I had so much trouble I went back to windows 7 installed from 4 backup discs. Now this won't work so I installed a full copy of windows 7 that I bought for my laptop (which is now dead). I am using that now but I have lost my touchscreen! It is a Sony Vaio VPCL138FG. I hope somebody can help me download the right driver! I installed a driver for it but it is not not working. Should I have installed windows 64 bit instead of 32 bit. Thanks in advance.
