i want to run the Flight Gear simulator on my Linux machine, but that computer is not connected to the web.
here is what i did to attempt to get the simulator on my Linux computer;
with my windows machine, i downloaded the .AppImage file onto an external hard drive.
i made a Flight Simulator directory on my Linux system.
i copied the AppImage file into that directory.
the instruction i found on the web stated that i needed to make it executable in 'properties'. i did that.
the instructions further stated it would run through the GUI if i double clicked on it.
that did not work.
i went into the command line mode, found the directory with the file in it. changed into that directory, carefully copied the complete name of the .AppImage file after the ./ i was told was the execution instruction, and no execution.
i got an error message that the file or directory wasn't found.
i carefully checked that i had copied the complete file name correctly.
i found no typographical errors.
i checked the note i had on executing a file and, in spite of finding no errors in what i had already done, i tried again.
and got the same error message.
