Minecraft vr play with modpack?

I'm playing minecraft on Curse with the modpack ftb infinity evolved. Now I wanted to gamble the whole time with my Htc Vive in VR. Only the installation does not work.

Have the file Vivecraft it needs installed in the Minecraft folder under Versions

The installation works but if I start the modpack via curse, I do not see a profile for vivecraft.

Does anyone know about this and knows what I'm doing wrong? Are the mods not compatible? Memory I give 6gb for the whole.
