To install the closet library you must first install the Microvellum ERP + Fluid Designer Application. The download can be found here.
Once the application is installed the closet library can be installed by selecting the Download Libraries button and clicking Download on the Closet Library Button. After the library is downloaded it will automatically be available in Fluid Designer.
NOTE: The Download Libraries feature is only available to users who have paid for the Microvellum ERP + Fluid Designer Subscription. The Free Version only comes with sample libraries and doesn’t include the closet library.
