Andrew, are you selecting these products in the product selection? Is this a fresh install OR upgrade?
It's a fresh install, and I selected everything mentioned from here
Did you tried deselecting the ones mentioned in the error pop up window? Also can you deselect everything and only select SOLIDWORKS and try to install? You can add others later if this works fine.
Contact you r VAR and they will assist you quickly.
During installation try to create an Administrative Image and you have a chance to get rid of this.
