After doing some more digging it appears that the reliance on vcomp140.dll is entirely because of Holocraft's use of Freeimage library just for loading some images. Holocraft itself does not have this dependency which is why v2.2 works but does not have the texture based optic generation mode working yet. I could re-work the texture optic code to use internal image loading code, or a different library, that does not have the vcomp140.dll dependency and fix the issue. I'm not a fan of requiring users to install things they shouldn't need like the vcredist.exe and if I knew that it was a thing before I used Freeimage.dll I would've not used it at all!
I'm just about to finish launching the new website and am very busy with that but I'll figure something out for v2.4 to get off the vcomp140.dll dependency. I am very sorry for the inconvenience :P Feel free to share any holograms on this forum that you manage to create :)
