ViewSet v07.11.36.00 (available on Web Downloads) is designed for use in MicroStation/J and as an update to the ViewSet functionality that was delivered in MicroStation TriForma v7.1. The default location for ViewSet in MicroStation/J is <drive name>\Program\MicroStation\mdlsys\asneeded\viewset.ma. To use ViewSet with MicroStation TriForma copy viewset.ma from the above location and paste it in the MicroStation TriForma location at <drive name>\Program\TriForma\mdlapps\viewset.ma (Note: This "paste" operation should overwrite the existing viewset.ma residing in this MicroStation TriForma location).
The result will be viewset.ma in two locations, and regardless if it is used from MicroStation or MicroStation TriForma the functionality will be ViewSet v07.11.36.00, the current version.
