Is there a way for GOG Galaxy 2.0 to allow users to specify the install locations for program and user data??

I do not want to let GOG Galaxy put anything into my C drive, (i.e., C:/ProgramData or C:/User.) I want to install Galaxy -- and all games and associated data -- on and ONLY on my G drive, (i.e., "Game",) which is an external drive that is portable/shared among multiple computers, (i.e., PC and laptop,) and simplifies data sharing, save games and my life.

How do I install Galaxy 2.0 or move whatever it puts in C:/ProgramData and C:/User into drive/location that I specify, and NOT... wherever?

Hello,

I fear you are out of luck on this one. There is no way I found that you can install everything where you want it to. The program itself and the game folder you can choose, but the "programData" part in unavoidable (the only way I found to not clutter my small c drive is through a simlink) - that folder is somehow 2 Gb on my install.

But you can just copy your game folder wherever you want (you don't need galaxy to launch a game).

Do as I did, install the client normally, move its folders to where you want them and create junction points for them.

I have also done the same for all the savegame folders that some games like to spray all over under my account folder, as restoring my OS from an image is a much simpler task when I don't have to worry about losing any recent savegames in the process.

if you go to the settings cog in the galaxy launcher, and then down to the installing/updating option, I will allow you to set whatever file path you want for the installing of games.

I have mine set up to my E drive, which is only used for game installs :D

The problem here is the Galaxy 2.0 app itself, not other software.

What is a junction point and how to create one?

I have GoG Galaxy on one of my older SSDs. For Cyberpunk 2077 I want to install it to C:\ which is my M.2 drive. Is it possible to point the folder to install to, to there? For reference my GoG games are on E:\ drive. Which is one of my two other game drives. I only put the newest games on my M.2.

Or can I change the 'Game installation folder' to C:\ and install Cyberpunk 2077 and leave The Witcher 3 on E:\ where it is now? Would that affect it at all? Would it redownload the game to C:\
My M.2 is only 500GB so I have limited room on there.

I have not actually tried it myself because I didn't need to, but I can choose the installation path for every game I want to install separately. The 'Game installation folder' setting seems to just be the default one that is auto-filled when installing games so you don't have to browse it each time.

It is a symbolic link to a directory, meaning that you can move a directory to from one place to another and then set up a junction point on its original location to point to the new location.

So after installing a game with the Galaxy client you could just close the client properly to not let it get confused about what you are about to do, move the installation folder to whatever other place you had in mind, open the command line, go the folder where you moved the installation folder and input something like this:

mklink /j [the name of the folder you moved] C:\Games\[the name of the folder you moved]

But you might not even need to worry about junction points as long as you are not trying to create a dedicated savegame partition like I have done, because the Galaxy client's import feature leaves the detected games wherever you had placed them, so all you need to do is to close the client after installing CP77, move its installation folder, start the client, let it remove the game from the list of installed games and then import it back.

You can specify install location when manually downloading galaxy client

The trick for this is DON'T download Galaxy from a link on a specific game. At a glance you'd think they all link to the same location, the same installer, but they don't. The Galaxy installer you download from a game web page is streamlined to install that particular game alongside Galaxy, and you don't get as many options (including installation location).

Instead, download Galaxy from their main link on the front page of their website. (Currently under the "About" menu at the top.) This one does allow you to choose an install location.

You are The Man. Thanks.
