1. Download and install from the PGI Compilers website: PGI Compilers Community Edition
2. Follow the set up instructions here: Installation Guide
3. Add some paths to the environment:
Under "path" variable: C:\Program Files\PGI\win64\17.4\bin
And then create a new varible called "PGROUPD_LICENSE_FILE" and add the path where license.dat is stored. In my case, it's: C:\Program Files\PGI\license.dat (must be the full path)
And we're done! :)
