I'm not sure what my system specs are, I know I have Windows 10, I have either 8 or 6 gigs of RAM, and if needed I could did my computer's packaging out of storage to see about the processor. I bought the Fallout 3 GOTY from steam. EDIT: The computer shows AMD A10-8700P Radeon R6, 10 Compute Cores 4C+6G 1.80 GHz.
The problem is the installer can't find the Fallout 3 .esm .bsa files. The files are in the Data folder, which is in the Fallout 3 goty folder. The browse option in the installer won't display the files in the Data folder just the Music, Shaders and Video folders, it will also display only the Fallout3.exe and FalloutNV.exe files in their respective folders.
I'm not a tech guy, and don't really understand what I'm looking at in regards to computers, so if it's not a tech issue and I'm just not understanding what the actual instructions are, then could you please explain it as if I were a grandparent.
