Open a terminal emulator (to get console) and type
chmod +x /home/evan/Desktop/ManageEngine_ApplicationsManager.bin
or more easily (because your terminal has most probably your home directory as your current directory):
chmod +x Desktop/ManageEngine_ApplicationsManager.bin
Or if you cd
to the directory Desktop, just
chmod +x ManageEngine_ApplicationsManager.bin
As you see, the first command (used only once after downloading the file) makes the .bin file executable (by default it should not be, for security reasons) and the second command then runs it. For that kind of binary files, simply type the full path name and filename to run it.
If you like using graphical tools, then on Ubuntu you can achieve it this way: right-click on the file on your desktop, choose Properties. Open Permissions tab and check the box that says to allow executing the file. Close the Properties window and try double-clicking on the file; either it runs, or if it doesn't, try the console method if it works better.
