However when I try to run IE9, the window opens, the blue loading circle spins, "not responding" appears, then the window shuts without anything appearing in the browser window.
My machine is a decent spec, and I've had no problems with IE8, or any other browser before.
Here are the things I've tried which didn't help:
-Installing IE9 via Windows update, instead of manually
-Running in "no add-ons" mode
-Disabling all add-ons manually
-Running the OS in safe mode
-Temporarily disabling firewall/antivirus
-Resetting IE settings in "Internet Properties"
-Ticking "Use software rendering instead of GPU rendering" in "Internet Properties"
-Re-registering dlls
-Running program as administrator
-Installing SP1
-Installing all critical/important windows updates
-Logging into Windows as different user
-Downloading the installer using a different machine (in case installer was corrupt)
I am now officially out of ideas. Anyone got any more?
