Subject: OPC Labs Contact Form - OPC UA using PHP - Forum Post Attempt
I am attempting to get support for using OPC UA via COM in PHP using Windows. [...]
Specifically to my problem, the UA COM service works fine when run by php-win.exe, but not using php.exe. The DA COM service works fine using both. Could this be a UAC issue within windows? Or perhaps an environmental variable that is missing from the install?
