3D Assets on Some Computers, Not Others.. Direct3D?

Hello!

So I have my game, from which I make a .exe build and distribute the data folder and the .exe to the three computers I could find. With two of them, the game works and runs fine, however on one of them most of the 3d assets do not visually show! The collisions are still there, but not the visuals: Tables, Torches, Terrains, Fences, Barrels.. They show up on some computers but not others, all using the same build and with hardware well above the minimum requirements.

When looking at the logs, I notice one major difference: "d3d11: failed to create D3D11 device (0x887a0004)" Was inserted in the troubled machine, below which it labeled the Direct 3d version as 9.0c.. However in dxdiag it says DirectX 11 is installed - could this be the issue? If so, how would I resolve it?

Many thanks in advance!
