Could not install Black Mesa

Black Mesa Archive In-game Issues (Mod)
#1

I am running windows XP, and during the set up of Black Mesa Source where I was to choose an install destination, I could not progress. Due to my C: drive being full, I tried to install in my D : and back-up E: drive, both of which had plenty of space. However the ‘install’ button remains grayed out and I cannot progress. Help please?

The installer is basically a 7zip extractor. You can alternatively download 7-zip (free) and extract the game data from BlackMesa.7z to C:\Program Files (x86)\Steam\steamapps\sourcemods\BMS

I have no idea why the installer isn’t working (it didn’t work for me either) but that basically gets around it.

Hate to sound like an idiot, but how exactly do I use this program to extract my downloaded BMS files? And how do I extract it to sourcemods/BMS since that file doesn’t exist yet?
