I just got crazy today, cause was trying to render my project edited on vegas pro 18 but that error just doesn't stop to anoing me.
I tryed to uninstall and install again several times and different versions of Net Framework, just didn't work.
I've updated my Nvidia driver, nothing changes.
After many hours trying different things, my friend got an Vegas Pro too, and rendered my project for me. But just to see if the problem was with my computer or Voukoder, he downloaded and installed Voukoder on his Vegas Pro 18 too and the same error shows up.
Just don't know what to do, because Voukoder saves me, my CPU is an G4650 and my GPU is GTX 1050 ti, without Voukoder it takes several hours to render. If has any way to fix it, help me please!
