When I tried to start Fallout on the road to the end of the game, it kept giving me the same error message. "Needs 20 Megabites of hard disk space to start the game". Which baffles me to no end.
When I set the program to start in Windows 95 mode, the game started up again just fine.
Is this game eating up RAM like no tomorrow or something?
Does anyone know what's going on with the game? I'm so confused.

It's a common error. usually adding or removing something from your trashbin can also fix it.

I thought these games were fixed to work with our OS's. Personally I don't think I will purchase anymore games here. Fallout runs slow as crap on my custom built quad core dual 8800GTX with 8 gigs of ram.

If you keep living looking for perfection, you'll die disappointed. :D
Try renaming/moving/deleting ddraw.dll in your Fallout folder.

Thank you for your attempt to help. Even though I can log into the game it still plays poorly. Maybe the game in and of itself blows. I should have expected that from an old game.

i have a similar set up -- quad core 6600 CPU, dual 8800 GT cards in SLI, 2 gigs of RAM. fallout runs perfectly. try installing the resolution patch and renaming/moving/deleting the ddraw.dll file. that's all i've done.

Thank you I will do that. Obviously since it plays flawlessly for you I must have something on my system it does not like. I am running Vista 64.

it could be vista 64. i'm running XP pro. i'm thinking that perhaps the program doesn't like the 64-bit OS.

there have been issues recorded on the forums here (where exactly, I couldn't point) of issues within x64, but those users eventually found a way around it (I can't remember if they posted their fix or not).

Thank you everyone for your help. I am going to search for answers regarding 64 bit O.S.'s
Thanks again.
