Any reference to an OS in the remainder of this document  \nrefers to the 64-bit version of that OS only.  \nDAT/EM Release version 8.1 is supported on the following operating system:  \n• Windows 11 Professional and Enterprise.  \n• Windows 10 Professional and Enterprise.  \nNotes:  \no DAT/EM generally recommends installing all Windows updates; however, if you are using nVidia 3DVision and a Microsoft Windows 10 semi-annual channel update greater than 21H2 , please check with DAT/EM to ask whether 3DVision still works with the newer channel update. Let us test it before you do.  \no DAT/EM software does not work with Windows Home Edition or LTSC (Long-Term Servicing Channel), formerly known as LTSB (Long-Term Servicing Branch) .  \nDAT/EM Software Installation  \n1. DAT/EM’s installation process will now place the version number so that Microsoft SCCM inventory will show it in the “Installed Software Product Version” list.  \n2. The installation for stand-alone MapEditor for MicroStation CONNECT has added the [datsiConn.ma](datsiConn.ma) file and a line to load it into the mapEd.cfg file that configures MapEditor in CONNECT. Additionally, Capture for MicroStation CONNECT has the modification for its MapEditor-only .cfg file, which can be activated by the DAT/EM Administration Tools’ CAD Enabler. These changes are related to detecting tentative point snaps. See more information in the “DAT/EM Capture and MapEditor for MicroStation CONNECT (64-bit versions)” section below.  \n(April 11, 2022)  \nHardware Locks/Dongles  \nInstall Microsoft Updates before applying lock reset programs. Network licensing should have the same Sentinel driver version on both the lock server and the local workstations running the software.  \n1. The Thales Sentinel driver version 7.7.1 is provided with DAT/EM version 8.1. This is an update from the one provided in the previous DAT/EM version. (2022)  \nSentinel Driver on Network Lock Servers: If you have a network lock on a network server, DAT/EM strongly advises you to install Sentinel 7.7.1 on the network lock server to match the version on the DAT/EM workstations. DAT/EM provides a convenient prerequisites setup file that installs the required Microsoft C++ redistribution files and the Sentinel 7.7.1 driver:  \n• Error!
