Microsoft DaRT 8 Remote Viewer on Windows 7 Operating Systems

Installing the DaRT 8 Remote Viewer on Windows 7

Microsoft’s Diagnostics and Recovery Toolset (DaRT) Remote Viewer lets you connect to and remotely view machines that are sitting in WinPE during an OS deployment — genuinely useful for watching a task sequence in progress or diagnosing why a machine is stuck at a particular OSD step without needing physical access to it. The catch is that DaRT 8’s installer is built to install cleanly on Windows 8 and above, and simply double-clicking it on Windows 7 will refuse to run. To get around this, extract the installer manually rather than running it directly:

msiexec /a MSDaRT80.msi

Running the MSI with the /a (administrative install) switch extracts its contents to a folder rather than performing a normal install, bypassing the OS version check that blocks a direct install on Windows 7. Once extracted, you can run the Remote Viewer executable directly from the extracted files without needing a full installation. This is purely a workaround for the OS check on the installer itself — the Remote Viewer tool works the same way once it’s running, regardless of which supported host OS you launched it from.

MDOP and DaRT Are Now Out of Support (Updated for 2026)

Worth knowing before you go looking for MSDaRT80.msi today: the whole Microsoft Desktop Optimization Pack — DaRT included, alongside AGPM, App-V, MBAM, and UE-V — reached its unified end of extended support on 14 April 2026. Microsoft isn’t currently pointing to a direct, officially-supported replacement specifically for DaRT’s Remote Viewer capability during WinPE-stage OSD troubleshooting; guidance for MDOP customers generally is to move workloads onto Intune instead. In practice, if you still need to watch a stuck WinPE session today, you’re looking at DIY options — baking a VNC server into your boot image, or PowerShell remoting where the environment allows it — rather than an official Microsoft tool. And of course Windows 7 itself, the OS this whole workaround exists for, reached end of support back on 14 January 2020, so a genuinely new deployment scenario needing this fix should be rare at this point.
