Seems to be not XP compatible (kernel error)
Can you wright full text of error?
The procedure entry point initializeCriticalSectionEx could not be located in the dynamic link library KERNEL32.dll
I think the cause is the new UnityPlayer.dll v2017.3, the other games works with v2017.2.
Just tried to replace it, but the player fails to launch due to mismatch with the exe. Maybe the soulution is to recompile the game with the v2017.2, if you want to try it, can you make a 32bit build, please? :P
Yes. Problem was at x64 only. There is new version available with 32-bit Win systems support.
Tnx but nothing changes: I've tested before the 64bit build on a 64bit virtual WinXP, and now this new one gives the exact problem on my real WinXP 32bit. I'm quite sure it's the new v2017.3 dll.
