I installed to my computer windows 7 to test them. Suddenly internet explorer cannot access any web page. Mozilla works normally. But internet explorer doesn’t not work. I tried to write on the address bar the router ip and again nothing. I have an error connection problem. I checked the ie properties/lan settings and everything its normal. I checked the firewall and its ok about restrictions. I made a reset settings on ie and again I have the same problem. I tried to reinstall ie8 and I have an error that says :your operating system doesn’t support this program. Do you have any idea what is happening?
