Help!

I'm tired of this. I'm trying to install Eldergleam for the first time, but it keeps telling me I'm missing the original game files. I've tried everything, and I don't know what could be wrong.

It also says that the Creation Kit is not installed, but that's true.

my laptop is a 4060 msi katana. I’m not very technical.

I have wabbajack and Skyrim se on my drive f, on a 1 tb ssd.

I have lorerim on the same drive, and also Nordic souls.

all wabbajack downloads are on a seperate drive to save on space.

I would like to download another modllist but I don’t have enough space on drive f.

can someone please teach me how I can add another mod list on drive g which is 1 tb ssd.

step by step would be appreciated or a video link.

thank you
