Since two days Kingdom Rush Venge4ance has stopped working on my system. It complains that it cannot find steam_api64.dll.
I have already re-installed the game, tried the repair option, and tried renaming Galaxy64.dll to steam_api64.dll..
It seems that something has gone wrong with teh last updates. Mixed up files?

Game has been running fine on my fully updated Windows11 system.

Tried to install through Galaxy on a different system: same problem. Tried to install using direct download files: same problem. In all cases the game tries to access steam files....

Same issue here. It broke after the update

The same here. I tried to start it directly with "Kingdom Rush Vengeance.exe" and here there is an error message about a missing file "steam_api64.dll".

I thought so. GOG obiously mixed up Steam specific files and GOG specific files. Should eb easy to fix.

FYI: I installed the Steam version of Kingdom Rush Vengeance, dated march 3rd 2022, on the same system, and that runs without any problems at all.

Same here seems broken :(

it works again, looks like they fixed it :)
