I downloaded and installed ie7 beta - for testing purposes. Then I uninstalled it and tried to reinstall ie6, but get the message: Setup has detected a newer version of Internet Explorer already installed on this system. Setup Cannot Continue.
I need ie6, and would ideally have ie6 and 7 installed for compatibility testing. So how do I get ie6 back and then how can i install ie7 again without it overwriting ie6?
I installed IE 7 awhile back. All I did was uninstall it through the control panels add or remove programs and I didn’t have to reinstall ie 6…it was just there. Make sure to check the “Show Updates” check box. Make sure all IE 7 items are gone.
… But you have to have two operating systems for that. Try this:
Download IE7, but don’t run the installer.
Create a folder called ‘ie7’ or something in your Internet Explorer folder.
Extract the files from the installer (that you downloaded) into the ie7 folder.
Create a blank file called ‘iexplore.exe.local’ in the ie7 folder.
Create a shortcut to the ‘iexplore.exe’ file in the ie7 folder and run it.
