Hi! Been waiting for SS4 - just bought it, installed as normal with downloaded files - it will load but pops up with a window featuring the error as follows:

failed to initialize ssl: unknown certificate verification error (537456641)

Install is AOK with file integrity, for a few momements I am able to see the menu. Is the game attempting to dial out?

Thank you all for your help, and looking to many more games to purchase in the future..

Not sure, perhaps contact support.

I didn't have this issue when I installed, nor notice any communications happening. Are you sure it was the offline installers and not the galaxy ones?

Hi nightcraw1er, I will report to the link you sent thank you.

for the past few years I have only used offline installers. I miss clicked for SS4 and it installed galaxy when I had walked away (I play off line single player). Once I returned and noticed I uninstalled galaxy and began downloading the offline installers as usual.
There might/must be some trace of this still on my system?

Yeah, have a look around, might be some traces left behind. If the offline installers give you them same problem, then I can check my copy by unplugging the internet cable, but I would be suprised (though not very), if it was phoning home. There have been some others that try that for varying reasons, was it victor gran which phoned home to get latest news? Anyways, you should simply be able to block those and the game work, if not it a serious issue that gog need to fix.

More testing.. When it crashes and produces this message, if I click the SS4 icon in the task bar - the game is available to play (even played a few levels!!), the crash bug reporting window is still open.

Two notes on the crash reporting - there might be a tye in some how? Bugzilla (which I do not have) is asking for a login to send a report and croteam dev bug reporter also attempts 50% of the time; some how between the crash reporting and the game it disables alt-tabbing (yes I did the termial cmd to disable this, something I found digging in the GOG forum) from functioning. I am able to alt-tab and run task manager, but it is un-selectable. Computer must be restarted at this point.

When I am able to access the game, adjusting settings (either AA or 3d render) really causes it to lock ;)

I ahve submitted a full report to Croteam/GOG. will keep this thread updated this progress.

Overall, still love GOG. This is the first challenge with one of their games in anyway (out of 43? owned).

You seem to miss a screenshot there you say it produces this message but never say what that message is). If it opens a bug report connection, you should be able to close that, and in your firewall you can block outgoing calls.
Yes, would be interested to see what they say. TBH the engine for SS4 is very unoptimised and buggy, so I am not suprised.

PATCH WORKS!!!

GOG is Amazing!

Thank you for the fast resolution everyone!!

You are welcome.
