I recently almost hosed my windows 7 installation, when I tried to install Internet Explorer 7 instead of Internet Explorer 9. The reason I tried to do that, was that I needed to have access to a really ancient corporate site, that looked hopelessly scrambled in IE9.
What I hadn’t realised was this was a recipe for disaster; IE7 is incompatible with Windows 7!! After IE7‘s installation failed (obviously), I was left with an impossible situation: I could not start any program and I could not even open up a folder with windows explorer. Instead, I would get a pop-up window with title “Explorer.exe”, and the very friendly message “No such interface supported“.
After much searching, I found the solution (first step, below). But then, IE9 would not open. It was impossible to uninstall it from the Control Panel (the process would fail) and it was impossible to re-install it (because a newer version would be found)! This problem was solved with the second step below…
Caution: Take the following steps at your own risk. They worked for me, but you should still do your own research and make your own decisions!
Step 1: Re-register all DLLs
- Click “Start”, then “All Programs”, then “Accessories”.
- Right click on “Command Prompt” and click “Run as administrator”
- Copy and paste the following command in the terminal window, then press <enter>:
[code]FOR /R C:\ %G IN (*.dll) DO “%systemroot%\system32\regsvr32.exe” /s “%G”[/code]
It will take some time, you may want to go get yourself a nice cup of organic green tea… and don’t close the command prompt window just yet, you’ll need it for the next step!
Step 2: Fix IE9
Copy and paste the following in the command prompt, then press <enter>:
[code]”%systemroot%\system32\regsvr32.exe” “c:\program files\internet explorer\ieproxy.dll”[/code]
That’s it, in my case it worked like a charm, but your mileage may vary…
