I installed IIRF on Windows 7 x64, but I have got problem. Every time when I try to views site I got error 500. I have no ideas how to fix it. Could you help me?

Luca, it looks like a permissions error.  I can't read the text, but I'm guessing Windows 7 cannot read or load the DLL.

( I've never tested IIRF on Windows 7. )

What I can to try to do?

I'm not sure that it best varian but look at picture to what I may try to push?

I tried to add IIS user with read, exacult permissions but didn't it helped

If it will be easy for you you may look at my PC with TeamViewer? Do you have any chat system for arrange about the time?


P.S. text on picture mean: "Call failed LoadLibraryEx in ISAPI filter"

I don't know what you can do.

I suggest you follow the instructions that I wrote in the help file, again.

I want to repeat that I've never tried installing IIRF on Windows 7, and I don't know if it works there.

I don't know if there have been changes for ISAPI filters on Windows 7 that would prevent IIRF from running on Windows 7.

If this hasn't been answered yet...

Luca - you're using windows 64 bit...the ISAPIRewrite4 module is a 32 bit application.

Fortunately, this is easy to work around with IIS7.

Please go here

That will explain how to enable 32bit applications on your 64bit machine.

I'd recommend you create a separate application pool to assign your web site too, if you're running multiple sites.

Good luck!
