Ganni1987: It installed fine for me.
My game is installed with the full version: setup_divinity_original_sin_2.5.0.11
Patched with: patch_divinity_original_sin_2.7.0.14
And then hotfixed with: patch_divinity_original_sin_2.8.0.15
I'm not alone with this error. As far as I understood, it affects all users who don't play the game in English and have pre v1.0.74 installers (game version, not installer version). Don't know which game version the 2.5.0.11 setup.exe is (should be 1.0.74, but giving the installers confusing names doesn't really help), but I have the old 2.
3.0.6 installer, patched with:
2.
4.0.10
2.
5.0.11
2.
6.0.13
Then the 2.
7.0.14 patch came, patching my game to version 1.0.107, but ending with an error because of an "incorrect version" of the LanguageSetup.exe - and now the 2.
8.0.1 patch (1.0.107 hotfix), doesn't install at all and tells me to download a newer version of the installer.
Looking at the bold numbers (3, 4, 5, 6, 7, 8), I shouldn't have missed any patch. Normally, I would completely skip future patches and just go on playing, but the last patch introduced this stupid game breaker, so I HAVE to reinstall anyway (or wait for a hotfix that works with a fully patched "old installer")...
