I'm developing a website and it's experiencing issues on IE9 (so I've been told). To debug the site, I need to uninstall IE11 and install IE9 (Windows does not allow one to have two versions installed simultaneously).

I already downloaded IE9 and then removed IE11 by going to Programs and Software in Windows 7, followed by choosing "Uninstall Windows Features", disabling "Internet Explorer 11", and rebooting my system.

However, even after uninstalling IE11, the IE9 installer will complain that "Internet Explorer 9 is already installed on this system.", which is definitely not true.

Is there any way for me to install Internet Explorer 9 on Windows 7 with IE11 installed?

You are trying to downgrade Internet Explorer 11 the wrong way.

Steps:

1. You will need to undo the changes you have made thus far by refreshing the Internet Explorer installation. Go to Control Panel, then Uninstall Windows Features, and enable Internet Explorer 11. Reboot the system.

2. Uninstall Internet Explorer. Go to Control Panel, then Programs and Features, on the left find View Installed Updates, under Microsoft Windows look for Internet Explorer 11, and then right click and remove the update. Reboot the machine, and you will have Internet Explorer reverted to the previous Internet Explorer you had installed. Windows 7 originally shipped with IE8 (REF: and some later releases had IE9 (REF: ).
