Currently I have SBP for my setup exe and I want to keep silent installation optional, so if user gives \silent command switch while installation then installation should be carried out as silent installation otherwise it should happen like normal installation. is it supported by default? or do we have to handle this manually in script, like first check for command line and see if \silent is there if it is then do silent installation or do normal installation?. If I have to do this manually then how can I set/unset silent installer flag?
