Import assets in makehuman 1.1.1

[Pancho1961]

hello, I cannot use makehuman 1.2 because the Intel video card in my PC seems incompatible. So I'm using version 1.1.1. my problem is this: there are compatible libraries for version 1.1.1, but I don't understand how to download them into the software to be able to use them. Would anyone be kind enough to explain to me the steps to follow? to include new poses for example in my version 1.1.1 thank you
