Does it? Do note the last few replies.

The ones regarding the GOG.com folder that I didn't have?

Edit: I thought you meant in this thread. Didn't realized you linked to another one.

It's a shame that Rebel Galaxy crashes on my Windows 10 desktop machine. Right after start-up. However it does play on my Macbook Air. So, there's that. Let me know if you fix the problem. I would rather play on my desktop.

I'm seeing the same symptoms as SKARDAVNELNATE: crashes on startup and I've never had a ProgramData\GOG.com folder.

I've found the solution for me: I had the game firewalled off from even chatting to even localhost and that was the problem. I let it talk to localhost only and all is well. The game definitely tries to phone home though. Specifically to UDP 514 on a computer in a network owned by "RIPE NCC". Might be French.

An interesting note is that the game was never *really* crashing. There were 2 small "pop-up" windows that popped up right after the game started. They were clearly from different system components; maybe one Rebel Galaxy and the other some some part of Windows 8.1. They both basically said "the game has crashed. Restart it". Clicking on one of them actually closed the game. Clicking on the other just closed the pop-up AND if I waited 10 seconds the game actually started! The other popup was still there and clicking it still killed the game. Sadly that popup was set to Always-on-top. I used some software to unset that and it ran just fine. I played like that for an hour.

Yesterday I had Rebel Galaxy suddenly start crashing every time I tried to launch it. I spent a few hours today following GOG's support page and updating everything else that could possibly be updated (which wasn't much since I keep the main drivers and programs regularly updated; most of the time was downloading on a slow ISP), but nothing solved the problem. Then I happened to find this thread and the newest post reminded me of something: when I last quit the game I had a notification from my antivirus (Avast) about the game wanting permission to access the internet, and I selected deny, because why would it suddenly try to go online after months of playing without access? I changed the permission to 'ask', and the game launched!

So... I don't know why the game decided it wanted internet access or it won't work, but thanks for the report that fixed the problem for me, scodebad2016!

I have never used Gog Galaxy and have always had Rebel Galaxy firewalled (as I do for everything that has no legit reason for network access). I had a couple of issues with Rebel Galaxy where it was causing my normally stable system to BSOD. While I was poking around figuring out the problem, I noticed that I had a lot of different versions of the MSVC++ redistributable libraries installed (somewhere around 30). After I cleaned all of them out and reinstalled only the latest revision of each version (6 versions, both x86 and x86-64 for a total of 12 redistributables), I was able to complete the game without a single further incident.

Gog.com game installers tend to install redundant or obsolete revisions of MSVC++ libraries to the point where there are numerous copies of each version conflicting with each other. I have already brought up the need for a checkbox in the installers to prevent this in the general forum. Until that is implemented, every time I install a Gog.com game, I have to hawk over the installer, waiting to see if a MSVC++ redistributable installer pops up so I can quickly click the cancel button and then check my installed programs to see if I was fast enough or if it did a stealth install, which has happened a couple of times already.

Solution, allow it through your firewall, the game miraculously works, enable the firewall, it doesn't start up, appearing to carsh on Windows 10 Pro or even crashing on some others.

Enable firewall and then it works again.

Wow. A single player game that requires internet or it crashes. I just love the digital age.
Solution, allow it through your firewall, the game will then miraculously work again, then when you enable the firewall again, it doesn't start up again, appearing to crash on Windows 10 Pro or even crashing on some others. I say appearing to because I get no error messages. A window just pops up and closes down again.

Enable firewall again and then it crashes/stops working again again (But only of you block the game).

Amazing. Wow. A single player offline game that requires the internet to be enabled and hates to be blocked in a firewall or it crashes.

I just love the digital age.

If you simply have to have your firewall on then let it through the firewall to run.

This is the case for a lot of games now, even on GOG :-(

Massive necromancy here, but the penultimate post isn't strictly true. The game makes several network connections, but only one is necessary. That being a connection to 127.0.0.1 - itself, basically. Block that and the game fails entirely.

The other network connections are to various places on the Internet. Some to GOG's sites, then some to various IP addresses that don't seem to have names associated with them. Blocking those causes no problems.

The game will appear to freeze upon loading if you block the external connections but allow the internal connection, but leave it for a little while and it'll suddenly pop up a loading screen. That'll reach the end and then freeze again, but after a short while it'll bring up the main menu and the game works fine.

My situation isn't necessarily the same as yours - I'm running it under Linux and my application firewall (OpenSnitch) gives you precise control over what connections are allowed (in this case, allowing everything to connect to 127.0.0.1 but blocking this particular executable from connecting outwards). On Windows, I think that Comodo firewall gives you that level of control, but I'm not particularly experienced with it.

Nearly 8 years later and this is still a problem. :(

As per other peoples posts I had to mess around with a firewall to plan an offline game to stop it from crashing when it loaded the main menu.

you guys do understand that 127 is not the internet and that game has issues because you are blocking Windows [not the game] with your firewall settings
