before the small subject a big thanks for all them HERE and all around
then the topic itself :
msfn site say about inno setup
QUOTE
Applications packaged with Inno Setup supports the /SILENT and /VERYSILENT switches (I'm not entirely sure on the difference between the two, as they appear to do the same thing)
the simple difference about "/silent" and "/verysilent" is the view of the progress and all windows of the setup progress !
ok it's not a so interesting stuff; but; the cool thing is the "/norestart" that give you a correct tightvnc silent unattended install and all fine because it's WITHOUT reboot/restart :
CODE
tightvnc-1.2.9-setup.exe /sp- /verysilent /norestart
just wait some few seconds and let's all the opened dialogs simply be closed

For the Inno Setup and some more sets, take a look at appdeploy @ http://www.appdeploy.com/tips/detail.asp?id=13
---and it's all done :]
