Quartus II 11.1

Run the application setup, select the (Paid) edition of Quartus II . Wait for it, or take a lunch break... When asked for a license, cancel the dialog box. Unzip the crack into the install dir e.g. \altera\11.1\ and overwrite folders/files. Run the LicenseMaker.exe from the install dir with administrator privilege. It will create a license.dat and set the required system environment variables LM_LICENSE_FILE and MGLS_LICENSE_FILE which point to the location of the license.dat Launch the program. When asked for the license, select the option to specify valid license file, and "Use LM_LICENSE_FILE variable" (or browse to the license.dat) You can do the same procedure (or verify the license status) from the program by going to the "Tools", "License Setup". Enjoy.
