I have 4 licenses being used (just background, not saying this has anything to do with the problem), but I am trying to install the free version on a 5th machine for testing. I am trying to install in unattended mode using the following command in an administrative power shell:

& ".\v8.1.7675_reflect_home_setup_x64.exe" /passive /norestart /l .\macriuminstall.log

Some brief dialogs are displayed, and the process ends pretty shortly after that. Macrium Reflect is not installed. I am getting the following output in the log.

I can install the free version successfully.

Any help is greatly appreciated.
Thanks, Dan

Ok, I'm just catching up to the new licensing model in which the free version (with backup capabilities) has been eliminated. I had not downloaded a MR setup file in a few months.

I was able to install using the new interactive mode, and I see in order to have backup, one must agree to the 30 day trial. 

I guess this is not available for the unattended install, yet (or ever).

No need to reply, just let me know if I've got anything incorrect.

Thanks, Dan
