Thank you for your reply.
I use an MX-15 Debian Jessie 32-bit remaster that fits on a single CD. I can install this system on a computer in less than 10 minutes. Since I test a lot of software and often feel the need to reinstall my system, I use it frequently. I have no plans to switch to a 64-bit system at this time. The executable files for Volleytile and Fly Hard are 32-bit files. I get the above error message when I try to start these games. The problem on my Linux system could be that a file is supposed to be created in a folder that does not exist on my system. *.?
Best regards
