Hello, please try installing 32 bit version of libcrypto and see if it works. Please let me know if you encounter any further issue. Thank you!
Thank you for your reply. The game require 32 bit version of libcrypto, libssl and libglu, but I stop because libglu is only 64bit in my debian buster. I am not so skilled to continue, I think that more "modern" distro (ubuntu or mint) work without problem. Thanks anyway!
