FYI, the command line switches in Kaseya for patch KB2579115 are incorrect. I had a ton of failures for this patch. On the security bulletin, the silent install switches are listed as
/q:a /c:"install.exe /q" /r:n
Kaseya is set to "/quiet /norestart". After changing the command line to the switches above, the installs are succeeding.
We put out an override for this yesterday morning - run a Get Latest Hotfixes and then try pushing it out again.
