So, putting it all together, I _suppose_ that the following happens:

- gksudo takes the command to execute and all its parameters in one single
  argument.
- it elevates its privileges and calls the shell to execute the command
  given.

Consequently the following may work:

Exec ["gksudo", Shell$("desktop-file-install " & Shell$(sPath))]

I read about some hacks in the code which would allow you to use "--" to
separate arguments to gksudo and the program being called. Maybe you can
experiment a little bit if the above does not work (I fear it). If, on the
other side, it does work, then I would suggest using the Shell instruction
instead of Exec :-)
