Just bought a new windows 8 computer, 64bit.
Firstly intalled my existing Total Commander 7.57 of course

I' have an old engineering software and install it also. This software starts with dos batch file.
Whenever I started it inside of Total Commander 7.57, it works.
But if I start it by clicking directly by its shortcut; it doesn't start...
If I install Total Commander 8.01, also not possible to start it in Total Commander...
What is difference in dos prompts in two versions of TC?
Any thoughts?
