I downgraded from 5 to 4 to use osCommerce and now I can't get anything but Page Not Found 404. Using SAPI and NOT CGI. I know the file is there and was working .. the phpinfo.php displays the same.

It gets worse .. our IT folk felt we should go back to PHP 5, we did.

We get the same 404 error.

We have totally openned up the directories to "stupid" levels of open security. No effect. Not running CGI .. running SAPI (php5isapi.dll). Website extensions set to the dll. If I try to run php.exe the Webserver will not start.

We're stumped .. two days on this. Stupid is as stupid does! Any suggestions greatly appreciated. I thought I had a future in IT .. until this!

I found an area that had the wrong entries and I made the changes from php.exe to php5isapi.dll .. something changed, now I get this:

Invalid access to memory location.

Where I made the change was:
IIS Manager> (choose all three, one at a time) Web Sites, Default, and a WebSite> Right Click>Properties>Home Directory> Configuration> Application Extensions

Scroll down to ".php", it was set to php.exe.. I changed it to php5isapi.dll

Now I get ..

Invalid access to memory location.

Did you ever get a solution to this problem as we are experiencing the same thing?
