Q: I get errors preventing the game from launching (Line LowLevelFatalError [File:Unknown]: or similar)
A: (Solution from Tomoushie)
1. Using 7zip for extraction
2. DirectX 11 and 12 installed (downloaded manually on internet)
3. Visual C++ 2012, 2013, 2015, 2017; 2019, 2022 installed (download on Microsoft website)
4. NVIDIA 516.94 and DirectX12
5. Game added in exception in Windows Defender AND added in ransomware protection exceptions in Windows Defender
6. Right click then "property" on the folder where the game was extracted, then uncheck "read only" in attributes at the bottom, and in "security" add all permissions to the folder. And finally, check the box "run as administrator"
