The requested lookup key was not found in any active activation context.

Normally I’m an up-to-date kinda guy so on my Windows XP install (through VMWare Fusion), I have the latest beta IE 8 running. Then I do my IE 6 testing through IE Tester. This normally works fine until recently I had a problem with Wufoo forms. Any page with a Wufoo form on it wouldn’t load in IE 6. I contacted them and they said they’ve seen the same thing, but only through “virtualized” renderings of IE 6, not through “real” installations. So I decided I was gonna uninstall my way back down to IE 6 and see if that would work. First you uninstall IE 8, restart, which brings you to IE 7. Then you uninstall IE 7, restart, which brings you to IE 6 (friggin seriously).

Fortunately, this worked, and it wasn’t Wufoo at all, those pages were running fine in a “real” instance of IE 6. But now I have a problem with a site in IE 7. IE Tester can’t test IE 7 unless you actually have it installed, so I needed to go back to Microsoft.com and install IE 7. And…

WTF. Great time for a nasty weird error with no solution in sight. I hate Windows. This is what happens when you click to download IE 7. You can close it, but then no download starts.

Thoughts? Email me or comment below. Also CodePen PRO is quite a deal. πŸ™

  1. I haven’t had this problem… but google-ing for an answer I came across this article:

    It talks about a second way to “manually” uninstall IE7:

    Sounds like this problem can be caused when you have part of the IE7 installation still hanging around.

    Hope this helps.

    Thank Jeremy! I think that’s exactly what the problem was. A little clean up and another restart and I had IE 7 back going again.
