Unity Plugins: Failed to load for Affdex SDK with error 'The specified module could not be found'

I am doing an experiment that involves playing an educational game (made in Unity) with facial tracking involved. The game can be downloaded here.

The facial tracking runs perfectly fine on my system and I have received data from several other random people on the internet indicating that it is working as expected. But some PCs gives me an error saying that they are not able to find the dll. How do I debug or even fix this?

Plugins: Failed to load 'C:/Users/....../ChemOCrypt-PC/ChemOCrypt-PC/ChemOCrypt-PC_Data/Plugins/affdex-native.dll' with error 'The specified module could not be found.

The dll file is clearly present there:

I also tried adding the same file to the fallback handler, i.e. inside the Mono folder, but same error.

Also, the dll is being loaded correctly on my PC, but another PC with lesser configuration (less RAM and no graphic card) is not able to load it. why so?

Try reinstalling it if it helps please give alike means a lot
