Hybrid VSviewer crash on windows 10/11 PC

[Selur]

Your laptop is 4th Gen Haswell so it's one gen later than my desktop.

That's the oldest cpu I can test with.

[@uote]As I said I have latest Windows 10 & 11 and vapoursynth fails on both so it's not old version of Windows.[/quote]
good.

The portable version of vapoursynth has different folder and files structure and does not contain vapoursynth.dll.

The additional folder in Hybrids Vapoursynth are from the portable Python version and vsViewers Qt dependencies.

2025.07.21.1 change log says "Vapoursynth: make sure Hybrid comes with a vsViewer.config on Windows"
What's that about ?

Without it vsViewer didn't start with the right environment, but did start.

Also when you "package up" vapoursynth for Hybrid, do you build it from scratch and add the binaries to Hybrid ?

What I did was:

• created a new empy Vapoursynth-folder
  
• downloaded 'Windows embeddable package (64-bit)' of Python 3.12 from https://www.python.org/
  
• extracted the Python download into the download into the 'Vapoursynth'-folder
  
• downloaded 'VapourSynth64-Portable-R72.7z' from https://github.com/vapoursynth/vapoursynth/releases
  
• extracted the Vapoursynth portable download into the 'Vapoursynth'-folder
  
• downloaded get-pip.py from https://bootstrap.pypa.io/get-pip.py and save it into the 'Vapoursynth'-folder
  
• opened a 'Windows Command Prompt'-window and navigate into the 'Vaporusynth'-folder
  
• installed pip by calling: pyhton get-pip.py
  
• opened the python312._pth in a text editor and added the following to lines above anything else in that file and saved the file
