"Win32: modify the LoadLibrary PATHS used" commit should be reverted
Basically it limits the filter to use dll's from the system32 only.
We (SVP) have a Vapoursynth processing filter that obviously depends on Vapoursynth libraries (vsscript.dll, which is NOT installed into system32 by default), which in turn depends on Python (again, NOT in system32).
It used to work just fine with all builds up to 2016-06-29.
