This new solution offers all the flexibility of the existing QTM floating licenses that were previously only available using Rainbow Sentinel server/dongles, but with no physical dongle required. The FlexNet architecture is ideal for enterprise-wide deployments and for secure facilities in which USB dongles are discouraged or forbidden. This solution is only offered to US Government customers at this time. The support files below contain instructions for getting started as well as Operating System specific support files, including Applied Imagery’s vendor daemon, LMGRD, and LMTOOLS. Please be sure to download the support files for the operating system of your license server, not the client machines. Operating systems supported for license servers are Windows 32-bit, Windows 64-bit, and SPARC/Solaris 32-bit.

    Current QTM Release Number: 8.0.4

    [/vc_column_text][/vc_tab][vc_tab title=”Sentinel Support” tab_id=”1431837776-2-12″][vc_column_text title=”Sentinel Driver Support and Download” disable_pattern=”false” align=”left” margin_bottom=”0″]Quick Terrain Modeler’s Floating and Portable licenses utilize Rainbow Sentinel SuperPro dongles and drivers. Applied Imagery always uses the current Sentinel driver version, but old QTM versions shipped with old Sentinel drivers. Please note that, in some cases, incompatibility in Sentinel drivers may prevent QTM from recognizing floating licenses (i.e., dongles) across a network, as the QTM client may not be able to communicate with the older Sentinel server (and vice versa). Therefore, it is advisable to keep your Sentinel drivers as up to date as your QTM version.

    Current QTM Release Number: 8.0.4
