Hello Zeno,
Question: What does Apache use the SystemPath for? Does Apache_MSI-Installer for Windows install some Apache DLL into the System Path during the Setup? I will Google this now.
If you start Apache with the "GUI" (Apache monitor), Apache is started as Windows service. --> a Windows service only nows the system $PATH (it's having it's own environment) and thus Apache / modules can only find DLLs in these dirs.
If you start Apache as console app with httpd.exe, it's using your user environment. In this case system $path and user $path are merged and Apache / modules can find DLLs in all those dirs.
Regards, Carsten
