The first time I start ProcessModel I get an error saying it can’t execute iGrafx or Flow80.exe.

ProcessModel 5.x and earlier versions, use iGrafx as the front end of the application. Therefore, if you have any iGrafx software already installed on your computer there will be conflicts with the version which ProcessModel installs and uses.

If you have a stand-alone iGrafx product installed (not related to ProcessModel), simply uninstall it, uninstall ProcessModel, then reinstall ProcessModel (see the steps below).

The other condition where you could get this error is as follows. If you try to install 5.x (or higher) over top of 4.2.x without uninstalling 4.2.x first, ProcessModel will not install iGrafx properly because of conflicts with the old version.

In either case you must:

  1. Uninstall iGrafx System using Programs and Features.
  2. Uninstall ProcessModel.
  3. Reinstall ProcessModel.
