The screen shot that I showed in this thread of the old dos game Sherlock is being run with version 0.74 of DosBox.
I'm not sure what you mean by "Mounting" the program.
In my case, I have the files for my game Sherlock located at
C:\Program Files (x86)\Sherlock
The EXE name for the game is "SHERLOCK.EXE".
So, to get it to run, I created a shortcut (see picture).
The target line is
"C:\Program Files (x86)\DOSBox-0.74\DOSBox.exe" "c:\program files (x86)\sherlock\sherlock.exe" -exit -fullscreen -userconf
First, we have the full path to where DosBox is installed. Then, I have the full path to the EXE that I want to run. The -exit is there so that once I exit out of the program, the command window that opens will be closed. -fullscreen is so that I run the program in fullscreen mode (not a window). Finally, -userconf is added to the end just to make sure I'm using the configuration file for DosBox. I think you can make changes to the configuration file for different uses, but I have not played around with that yet.
That's all I had to do. So, I would think in your case, you would be able to have something like this
"C:\Program Files (x86)\DOSBox-0.74\DOSBox.exe" "c:\one\one.exe" -exit -fullscreen -userconf
Take note of the placement of the " ", as you need to use them if your directory names have spaces.
