I have been trying to get a system state and files/folders backup of my windows server 2012 R2 but the MARSAgentInstaller.exe fails. My server, agent installer, and vault credentials files are all up to date. I also made a rule in my firewall to allow all connections for the MARSAgentInstaller but that didnt change anything. I cant seem to figure out what's causing the error and I've been trying for 3 days now. In the screenshots you can see the error, then after clicking ok the second windows pops up saying "Error starting the Microsoft Azure Recovery Services Agent Setup Wizard"76822-azure-error.png

    @Jack Was able to resolve this issue by uninstalling the MARS agent and install it again.

    For me the issue got resolved after starting service Windows Update (Service Name: wuauserv) which was stopped. I was also getting same error whet tried to installed MarsAgent on win2022 server. I tried many articles but no luck. When I selected installed with window updates it shown me error for window update service. So I checked Windows update service found it was in disabled state, hence I set startup type automatic and started service then tried.
