I am trying to install PHP5 on a Windows 2003 Server x64 machine and have run into a wall. When I first got it installed I was getting a 500 error that read "%1 is not a valid Win32 application". A little research revealed that I needed to run CSCRIPT ADSUTIL.VBS SET W3SVC/AppPools/Enable32bit
AppOnWin64
1 from a command prompt so that IIS would treat PHP as a 32 bit process. However, I have Exchange Server 2007 running on this same box and once I ran this command, Outlook Anywhere and OWA stopped functioning. Is there a way to install PHP on a 64 bit OS with running the Enable32bitAppOnWin64 command?
