Without knowing what you've tried:

Apache and IIS run independently of each other. They need to be on different ports. I've successfully setup Subversion, which uses Apache, on an IIS machine, but the installer did all the work.



>I have literally spent over 16 hours now trying to get PHP to work with IIS 7 on a Vista Business SP2 desktop. It's a no go. No matter how many forums I've visted and no matter how many technical articles I've read, and all are quite similar, and no matter how many enviornment variables I've appended, and no matter how many things I modify in the php.ini file, no combination seems to work. I still cannot render one PHP page on an IIS 7.0 server.

>I can't tell you how many times I have rebooted my desktop after making untold numbers of changes to various variables, files, etc. If there is some authority on how to use PHP with IIS, I do not know who he or she is. I am still going to try to get PHP to run though.
