This is the error message I got when I downloaded and upgraded from a perfectly functional Adobe Reader 9.5 to Adobe Reader XI. It did download in protected mode but I didn't have any problems with it last time I upgraded and downloaded in protected mode. My OS: Windows 7 -64 bit with IE 10. I hope this doesn't have any problems with my antivirus software ....since my last blue screen of death experience >.< due to a trojan horse virus that wrecked everything ....so bad I had to use system restore. So, I bought Norton 360 with the intention of having my computer like Fort Knox! However, I have no idea how some of the stuff works on it though...lol
Can you help me please?
