Tried to install from gog, game was fully downloaded but install registration could't be finished.
after that the install button is greyed out.
can dowload and install manually.

same here. Could not update to the latest version, so reinstalled from scratch. Play button is grayed out, and the game is on a neverending update loop. INSTALLATION FAILED: CONNECTION PROBLEM. Restarting GOG galaxy makes you loose 32GB of temp files.

Same for me !

Trying to finish the installation since 2 days, Retried dozens of time, its at 100% (0.2mb) then fails
Did Verify files too, same thing happens.

Retrying by re-downloading all sub-chunks.

One of the files in the deployment is messed up, GOG or Owlcat needs to correct either the data or the manifest.

not sure if it helps, but yesterday I had 2 patches (the second one was from 2.0.3_BROKEN to 2.0.3), I just updated now after the galaxy update, the game's displayed version was "unknown version", it downloaded 2.1 Gb of data and completed the upgrade, but now it says I'm on version 2.0.2

really weird, hope it gets sorted out
