Answer by csgeek for Can't install .sh file

Well, for one the file you linked in the your URL is a .run file not a .sh file.

so if you try to run it using bash there's no guarantees that it'll work.

The only thing you didn't try in your list of attempts is to run it using

./filename, or in this case.

chmod a+x N750-GPL-1.00.42.run
./N750-GPL-1.00.42.run

Also, if you do get an error when you do ./filename.sh. (I do see that you tried sudo ./filename.sh ) it would be helpful to see what the error might be.
