Hi.
I got a error message when I try to start the game on Windows 8.1.

i meet the same problem bro ,have you solved the problem ?

After few months I switched from W8.1 to W10 Pro. The game no longer had this problem and is running fine.

i use win11 now,maybe this game only support win10,thanks for replying my question.

Same here, same error message, same OS (win11) with new laptop.

Try to enable the W10 compatibility mode, maybe this works

same error, running as administrator, applying patches, re-installing and compatibility modes don't fix this

Same error -- I was able to run the game by going back to version 1.4.3 (turn off automatic updates, Manage Installation -> Configure, Select 1.4.3 under updates.

worked for me.

I have the same problem - on win10

Why no one is finding a solution to this !!!
