Hm, here is the full PATH variable. I'll try to spot which DLL is failing to load on Monday. C:\Program Files\Python36\Scripts\ C:\Program Files\Python36\ C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common C:\Windows\system32 C:\Windows C:\Windows\System32\Wbem C:\Windows\System32\WindowsPowerShell\v1.0\ C:\Windows\CCM "C:\Program Files (x86)\Common Files\EMC" C:\Windows\CCM C:\Windows\CCM C:\Windows\CCM C:\Windows\CCM C:\Windows\CCM C:\Program Files (x86)\Common Files\EMC\ C:\Windows\CCM C:...

I checked the PATH variable on the Windows 7 machine, and all of the paths in PATH are absolute.

I tried it on another machine, and the problem did not occur. That machine was running Windows 10. The machine where the problem occurred was running Windows 7. What version of Windows did you use to test?

DLL load fails when on any drive other than C:
