I have V.2 of the game, so I'm trying to download the downgrader, I did so I selcted E disk drive because thats where it is, but it says I need more disk space, I know how to clean up my disk space, but not for disk drive he, so how do I?

you can download it to any location.

you install it (the downgrader) to where the game is installed. (Program Files/Rockstar/GTA_SA)?

you can't 'make space' on a DVD drive.
Or to put it another way you don't install the downgrader
to the DVD.

Hmm...the only one that hasnt worksed so far was the default one C:\Program Files\Rockstar Games\GTA San Andreas,which gives me an invalid directory message but if I try the f drive or any of the others, it says that a disk needs to be in there

?

well then

Where is the game installed? Install the downgrader to that
directory.
Do you actually have a DVD or is this a Direct to Drive version? I don't know if you can modify direct to drive stuff.

You shouldn't have to download it to a specific location.
Just anywhere you have space.

There should be a readme.txt with the download or at the download site that explains what to do.

You mught have to have the SA DVD in the DVD drive inorder to install the downgrader but I don't know why.
You of course need the DVD to play,

well im sure ive got the dvd, and it only works if i use the E drive, ill check out the read me file though...
