[HELP] Avisynth not working

[Selur]

I'm using an old version,..

and that is where my interest in it died

So what can be done to make QTGMC work in Hybrid?

With some mysterious version from X years ago: no clue.
Too much changed since then.

Try not to update from such an old version, deinstall it completely and install a current version.
If it still doesn't work, create a debug output level 9 (!read the sticky!).

Cu Selur

Ps.: As a side note: Hybrid does neither install any version of Avisynth or Vapoursynth system-wide.
