Hello I'm trying to install the GOG Galaxy client and keep geeting "The Source File is Corrupted" when I get to the installation point. I have attached the relevant logs:

2025-02-07 17:09:34.088 Extracting temporary file: C:\Users\user\AppData\Local\Temp\is-RFRAC.tmp\VC_redist.x86.exe
2025-02-07 17:09:34.132 Source file corrupted: zlib: Compressed data is corrupted.
2025-02-07 17:09:34.132 CurStepChanged raised an exception (fatal).
2025-02-07 17:09:34.132 Exception message:
2025-02-07 17:09:34.132 Message box (OK):
Runtime error (at 126:59):

The source file is corrupted.

I can download and install other things just fine. I tested other browsers, offline client installer, running as admin, etc. with no luck. I am running 64 bit Windows 11 Pro, version 24H2. Any help would be appreciated!

Have tried downloading the entire client a 2nd time? Perhaps testing on a different pc, to rule out whether it is your pc or the client?

Perhaps it is UAC in windows, depending where you try to install it to.

If you want to, you install some stuff yourself, for both 32 and 64bit, by each edition.

If you save them, make folders for each one. Otherwise it will be a mess. Same file names.

Have you tried living without the client? It's really, and truly optional. Detrimental, some might say.

The support forum for Galaxy can be found here: https://www.gog.com/forum/general_beta_gog_galaxy_2.0

Going by everything I read from time to time, here on the forum, about Galaxy, you may consider yourself lucky, that that piece of software won't install on your PC.

I've done a fresh download for the last 10 install attempts with no luck. I was able to download and install on my laptop so it looks like its my PC.

I don't think its UAC, its set to the normal recommeneded and I'm on an admin account and have run it as admin.

Could you elaborate more on the VC redist and making folders? I have a feeling the path is the issue. I have a lot of programs installed for school that involve coding so I may have messed something up. I've done a fresh install for VC with one or both (x86 and x64) with no luck.

Well I noticed the client tried to install that program. It is needed by a bunch of games. So I figured if you get that installed, it will be one less problem for you.

As for the individual folders. It is because the files all have the same name. So to structure a folder system to match each file with what it really is, would help you.

example:
Visual Studio 2015-2022
x86
x64

^^^^ add the files to the folder it goes with. The go down the entire list getting each file and detail the year and subfolders in x86 and x64 accordingly. After each file is structured, install all of them. Then you are covered. I would also recommend
getting the .Net stuff as well. V3.5 is a little tricky to install though.

Then again, you may need to figure out whats wrong with your pc first.

Hello, • Install both vc_redist.x86.exe and vc_redist.x64.exe then restart your system.
• Download the latest full installer, setup_galaxy_2.0.80.33.exe. Make sure it's fully downloaded. It should be 288,029,680 bytes in size with F6C4FAC121DC744200053A4679B406EB as its MD5 checksum.
• Check if there's enough free disk space on drive C: and wherever the temp folder and paging file are kept, if they're on different drives.
• When you run the installer, check if your antivirus is placing any of the extracted temp files in quarantine.
• If the problems persist and you haven't already done so, open a support ticket.
