--- Comment #13 from Kim Lindgren mrkimm@gmail.com --- Sorry for double comments. I copied over bcrypt from my Windows 10 virtual machine and tried running the Steam version with bcrypt set to native. The application fails instantly with '"bcrypt.dll" failed to initialize, aborting'. I'm assuming the native bcrypt dll depends on another native dll, but not sure which.
While I fetched the native dll I noted that there was another dll named bcryptprimitives, which I also copied over. I tried to override that library as well but it made no difference (exactly the same error).
I should probably mention that both my virtual machine and the wineprefix is 64-bit.
