Design Modeler requesting Blade Modeler Increment, acfx_bldmdlr, Blade Modeler

This is due to a preference setting under DesignModeler that is set by default to look for Blademodeler license as well (from 2021 R1). You can unset this by following the steps below:

Under DesignModeler --> Tools --> Options --> Addins --> Change BladeModeler licensing to NO (Normally, it is set to "if available"), then close DesignModeler and open it again
