Hi, I just found your nice blog, whilst looking for some notes on parts of SAS admin, and I thought I'd comment on this. Most likely it wasn't specifically using a plan file that got you out of trouble here, but the set of components selected by the plan file. Most client side SAS components do not check the platform of the license for installation, just that you have a valid license that is in date (for example you may have an Linux license with Enterprise Guide on it along with the other server software, even though it cannot be installed on Linux). If when selecting components manually, you selected SAS Foundation or something else that does a proper license check then you would find, the wizard would not proceed without a matching OS.
