Hey all! Hope you're well. Now I'm "one of those people" A retro gamer as such and I have a really cool Windows XP machine that I use for all my old games, Well XP era old. My Win95 and 98 machine are for the older ones. But I've been trying to get Fallout 3 working on it and I just can't. I cannot find a version that isn't packaged with Steam, Which sadly as of 2019 is no longer supported on XP. I have an original disc and all but still sadly.... Steam. So my question is, Is there anyway I can get the GoG version working on XP? Or does anyone know how... Thanks for your time!

Could older version of GoG Galaxy help?

Ultimately it would depend if that version runs on 32bit... But I'll try! Thank you! I'll reply with how it goes

Well, the client does not change the game, but maybe you can access older versions of the game.
If the client is old or not however won't make a difference. What you can do, is to install any client on a newer PC, see if you can install a older version of the game (usually GOG supports up to six legacy versions) and then copy that one over to XP.
Some games also have a 32 bit patch, check the download page on the website

I still use Windows XP.

I will never let go of Windows XP..

I still think Windows XP is usable.

I will only let go of windows XP when I am dead.

From my cold, dead hands!
:D

Honestly if XP still had browser support and a few others I'd use it daily.

You could try extracting the files from the installer using InnoExtract.

Doesn't Palemoon and Seamonkey both still run fine on XP?

Ya know I don't actually know. Those are new to me but I'm going to try them for sure!. There was a version of Opera that was supposed to have XP support but it doesn't actually work

For XP you want MyPal68 by Feodor2 or the browsers (typically NewMoon) by roytam https://rtfreesoft.blogspot.com/search/label/browser
There is also a fork of Chrome by the Chinese that others have supposedly removed the telemetry from if you're brave enough to try it. https://msfn.org/board/topic/182876-360-extreme-explorer-modified-version/

As far as the Steam ver of Fallout 3 I don't have since I have my original copies but typically for Bethesda games you can use Steamless (Don't ask here just google it) to remove the Steam requirement for your copy so you don't have to use Steam. Also if your copy is the newer version of Fallout 3 with GFWL then you'll need to use xliveless. If you have both F3 and New Vegas you should look into using TTLW to integrate both.

My kupuna still has his MS-DOS Gateway 386 and 3 1/2 inch floppy disks with game SW on them. We are priviledged to be able to witness a real-life T-Rex in person. La Dolce Vita.

Ooh dear, here's a thread that needs a title spellcheck...If you're encountering errors relating to the GOG Galaxy DLL (which is present even in offline downloads of single-player games) then the Good News: Galaxy.dll breaks XP-compatibility in good old games thread has a solution in post 246 by SonicBlue.986.Check out the Roytam1 Browser Updates for XP-compatible versions of Pale Moon, Serpent and Basilisk browsers. In fact, you need to be using these since GOG has changed its account games library page so it won't display on older browsers.

However you can still use older browsers for general web surfing - Opera 12.10 is still much faster than anything from the Firefox family and while some site "bells and whistles" won't work, I'd far rather do without the website chrome in favour of faster access.

Not sure if it's a factor or not, but MS stopped supporting Win XP in 2009 and Fallout 3 came out in 2008. Any updates to the game may have stopped it working with XP ... presuming it did work with it when it was first released.

If you own the game, then to get a copy that works, try an abandonware site for an old enough version.

No luck with anything so far. I think Fo3 might just be too recent for my XP machine. Short of finding a version of professional and getting a 64bit OS. Oh well! I still have oblivion and fallout 1 and 2 on it.
