auto run manners ?

I have a nsis installer that I would like to launch automatically once downloaded...

do I need to do something to the nsis file to make it auto-run once downloaded to the user's desktop...like make it self-extracting?

also, am I breaking any 'rules' by doing this ?
Is it better manners to let the user double click on the nsis app to launch it instead ?

a good portion of my users will be on corporate networks. I heard some of those networks delete any .exe file downloaded automatically.

from those who are experienced with this sort of thing, what would best serve the user ?

It's up for the browser to decide whether to execute your installer automatically or not. This post contains some information about doing this with IE.

thanks...I'll check that out
I looked in the archives for an example...does anyone using nsis have a working example of something like this

NSIS is great by the way...my app launcher/installer runs quite wonderfully
