R1c088: After installing Divinity: Original Sin - Enhanced Edition, the game try to sync cloud saves, but it seems it doesn't work, because nothing happen.

Sarafan: It's only a workaround, but try to run the game without GOG Galaxy. To do so, go to the folder where you've installed the game and run the EoCApp.exe file. You can also make a shortcut to it on your desktop, so you won't have to go to the folder each time you want to run the game.

R1c088: I tried, but it tells me that it can't go on because MSVCP110 was not found.

nightcraw1er.488: It sounds like (and there seems to have been hundreds of these threads over the last week) that you are missing a c++ extension.

The game installed should install this for you, but you can cancel and I do not know if galaxy is broken and not doing this.
My recommendation, as always, is to not use galaxy, download the offline backup installers from the website, install fully from there to a folder not used by windows, eg c:/mygames, and then run it from the icon.

I suspect, given the number of these threads that galaxy is somehow broken and not installing things correctly.

sanscript: What nightcrawler said. Some of these older games seems to have a hard time functioning with Galaxy...

In case you need to manually install Visual C++ libraries: https://silent-install.net/software/microsoft/start

nightcraw1er.488: Yes, GOG really needs to address this, there have been hundreds of these threads all with the same issue over the last week so obviously something has broken with galaxy. Will put in a ticket.
