I followed some tutorials to mount the program and everything works as it should work.
When i type 'dir', the correct files appear so i think the mounting was done correcly.
The install text document that comes with the programm just says: "open the .exe file and follow instructions on screen"
However, when i try to open the .exe file to install/run the program, i get this message:

When drag the icon of the .exe file to the DOSbox icon to open the programm, the same message appears...
Anyone who can tell me what to do to run the programm correctly?
Thanks a lot!
