trying to install php/apache help needed

i have iis installed for creating asp apps, but i don't have a clue how to free up the ports it is using to install and run apache/php.

Sounds like problem to have two webb-servers running on the same machine.
Cant you install php on the IIS-server? Or shut it down if you want apache/php instead?

whew! finally got it working. iis on localhost and apache localhost:81. they run at the same time, i love it.
