Hi, I use PHP 5.2 on Vista x64. Rather than use the registry we use the PHPRC environment variable to determine the ini file location. This works the same on all editions of Windows - x86 and x64. Would this be a good alternative to use? In direct answer to your question though, the Wow node is for 32 bit apps under x64 windows - I would expect PHP to be looking there, just like any other x86 windows app. Don't forget to make sure IIS (if that's your webserver on Vista) is in WOW32 mode, otherwise php won't run at all.

Is there anyone who here running 32bit PHP on a 64bit Vista platform who could help me with a IniFilePath registry query. The question relates to the use of [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PHP] vs [HKEY_LOCAL_MACHINE\SOFTWARE\PHP]. I'm on 32bit XP and have no 64bit Vistas available. Any comments would be appreciated. Regards, Richard. -- ----- Richard Quadling "Standing on the shoulders of some very clever giants!"
