Hi im trying to run cfm page in iis7, ive moved the file into the iis7 webroot folder

when i run the server the messenge says:

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

please help ?

I’m getting the 404.3 error (Error Code 0×80070032 ) on 32-bit Vista Business. Anyone know how I can resolve this?

Thanks Chris.

Although, I had added the MIME type for .php to “application/x-httpd-php”, so it was being served without the error you’ve shown above, it was serving the PHP code as plain text.

All good now. I’m guessing you just saved me another hour or so

God. Thanks for that.

Just wasted 30 mins at work trying to work this out. Don’t think I’d ever have found it myself.

OMG! One day of my life that I will never get back was spent trying to work out what I had done wrong. Thankfully, after stumbling upon your entry, it was fixed in only a few clicks. Thank you so much

I just posted a solution to this, but I noticed that there are other solutions in your comments – From Buzz on May 1st.

Oh man… this was key: “found an option ‘Enable 32-Bit applications’ in the ‘advanced settings’”… You should re-write the guide and make this a step. Your web site is literally the ONLY one that says it. Thanks!

While searching for a solution to this problem I found this blog. After a bunch of fiddling with IIS 7, I found that by default, IIS on x64 will not allow 32 bit processes to run. You need to open the IIS manager, and select “Application Pools” in the left tree. Then from the new options in the right tree select “Set Application Pool Defaults”. From there, just change “Enable 32-Bit Applications” from false to true.
