mrkgnao: That's an unrelated issue. It's a broken link on GOG's side. If you click it (the Cleared for Transfer 32-bit installer) in your GOG library in your browser, you'll get the same 404 error. The only way to fix it is to open a ticket with GOG support. Unfortunately, in my case, GOG has won. Their intentionally annoying ticket system makes it so that I don't want to open any more tickets. You're welcome to do it, if you want.
P.S. If you have them, here are more broken links of more or less the same kind:
"republique (Manual (coming soon) )"
"warhammer_skulls_2022_digital_goodie_pack_goodies (Warhammer Chaos Gate)"
"wasteland_2_directors_cut (Wasteland Avellone Novel (coming soon))"
Their broken links situation is complicated.
First of, they have two types of broken links: Intentional ones and unintentional ones.
Intentional broken links are used like labels in the files list (ie, "don't worry, the dlc is in the installer and this label here is to reassure you" or "manual coming soon... yeah right"). Unintentional broken ones are genuine downloads that are intended to work, but are broken.
There is a way to differentiate the two during the download metadata dance (the specifics don't come to mind atm, but I can dig them up from my code when I'm back from vacation if you like, I don't want to look at code on my tiny laptop screen... strains my aging eyes).
However, it might ultimately not matter, because on my end, I've managed to talk to a human for the broken links and they don't seem to be fixing them.
I don't think this is something that support can fix. Either they don't have vertical integration for their game files releases (ie, the game owner has control over the release process and they can't override anything at the store level) or otherwise fixing broken links is dependant on their dev team and they are currently too short on manpower to address individual incidents as they pop up.
