Setting up the PSCAD X4 Free Edition

The PSCAD X4 Free Edition may be run on a Windows operating system (Vista SP1 or later) with an Internet connection. The following information may be used to set up your software and licensing.

Please proceed as follows:

  • System requirements for this setup are as specified in this article.
  • If you do not already have a MyCentre user account, set one up as per Step 2 of this document.

  • If MyUpdater is not already installed on your machine, set this up as per this article.

The Update Client ("MyUpdater") is used for installing the PSCAD Free Edition as well as required GFortran compilers.

  • Install the PSCAD Free Edition using MyUpdater. Also install one or both of the GFortran compilers, as a Fortran compiler is required for building your PSCAD projects.

Some corporate networks block MyUpdater activities. If you encounter any MyUpdater login or installation issues, please see this article for troubleshooting suggestions.

  • Log out then log back in on your machine.

  • Launch "MyUpdater" from your Windows Start menu, then use MyUpdater to launch the PSCAD Free Edition.

  • Test your compiling environment as per this article. If there are no build errors, then your software is ready for developing your own projects.
