I recently installed IE 10 on Windows 7. The initial install was smooth and all looked good, until I opened a website (cnn.com) and got a blank screen. So I decided that the pre-release was not ready, and decided to uninstall it and reinstall IE9.
This is where the problems started. I thought I had removed IE 10 from my system, but when I tried to install IE 9, it said I had a more recent IE version and the installation stopped.
So I thought I should remove the Internet Explorer folder and got an error message about TrustedInstaller. So I took ownership of the folder for my userid (John). Now when starting Windows Explorer I get the following message:
You need permission to perform this action: You require permission from John-PC\john
I just gave ownership of the folder and its subfolders to John-PC\john.
How can I get back IE 9?
