We are regularly deploying OES Client.
Now we fail to do a silent setup. it looks like IR10 is just ignoring the /acu switch compleatly!

from Powershell we usually start it like this:
 Start-Process 'setup.exe' '/ACU /NCPF:Settings.txt' -Wait
And yes of course the settings txt is created with the current nciman.
Also if we only run
"setup /acu" IR10 displays the installation dialog.

IR 8 works fine like it allways used to.
