Linux versions of LINGO are distributed as a Run file, titled LINGO-LINUX-64x86-15.0.run, which is an automated installation program that will do the work required to set up LINGO on your Linux machine.  Once you've copied this file onto your machine, you should first set the file's protections so that it is executable. You may do this by opening a Linux terminal window, changing to the directory with the Run file, and entering the command:

chmod 755 ./LINGO-LINUX-64x86-15.0.run -v

You may then start the install program by entering:

./LINGO-LINUX-64x86-15.0.run

If you are installing LINGO with normal user rights, the install program defaults to putting LINGO in your $HOME/lingo15 folder. If your LINGO license permits multiple users, then you can install LINGO as a super user, in which case, LINGO defaults to installing in the /opt/lingo15 folder, where it may be accessed by other users on the machine. In either case, the default location may be changed to suit your needs.
