You are right, our QA team became over-cautious for a certain time and included VmACheckIsDC
action to block installation of Veeam One Client on a DC since it`s not the best practice as you probably know.
Sorry for the arisen inconvenience.
As a workaround we recommend to do the following:Download a Transform file here.
And set a path to it manually:
Msiexec.exe /i <full_path_to_veeam_monitor_cln_x86.msi> TRANSFORMS=<full_path_to_MonCln80DC.mst> /lv*! <full_path_to_logfile>
msiexec.exe /i E:\Monitor\veeam_monitor_cln_x86.msi TRANSFORMS=D:\exchange\vo80\MonCln80DC.mst /lv*! D:\exchange\vo80\log.txt
Thank you for the feedback, Dean!
