Hi,
I downloaded the AppImage clipgrab file and made it executable but it 
won't run.

fred@ragnok:~$ ls -l ClipGrab*
-rwxr-xr-x 1 fred fred 95575752 Nov 21 07:10 ClipGrab-3.9.2-x86_64.AppImage

fred@ragnok:~$ ./ClipGrab-3.9.2-x86_64.AppImage --help
bash: ./ClipGrab-3.9.2-x86_64.AppImage: cannot execute binary file: Exec 
format error

Any ideas how to fix?

Best regards,
Fred
