I had tried that. And I just tried again.
Trying to launch \monitor\Veeam_monitor_cln_x86.msi complains "Local Administrator privileges are required to install the product"
There's no right-click "run as administrator"
Troubleshoot Compatibility doesn't give an option to change the msi to "run as administrator"
From an elevated command prompt I tried "msiexec /a veeam_monitor_cln_x86.msi". This requires a network drive that it installs a "server image" of ONE. Unfortunately, the veeam_monitor_cln_x86.msi there also fails with "Local Administrator privileges are required to install the product"
And, yes, my account is in the Administrators group on the machine (not domain joined or anything like that)
Any other ideas?
