IBM Client Application access - how perform the silent installation ( this post contain the correct command .. )

Last week my colleague  Fabio Grasso working with a customer has noted an error in the ICAA documentation that prevent silent installation to work correctly:

here in the document page  is reported the following wrong command

setup.exe -s -a /s /v"/qn"

but to be able to perform a silent ICAA installation the correct command to use is the same needed for Notes

setup.exe /s /v"/qn"
