How to create a stub installer

[artistscope]

We have some download locations that are still well linked but we cannot redirect them and think it best to replace the installer with one that downloads and runs the latest installer from our main download site (the one that is kept up to date).

So I am thinking of stub installer like the browser makers insist on using, ie: download a small installer file which then downloads the real installer.

Any hints or tips as to how to do this using SUF will be most appreciated.

I have found some help for using HTTP.Download but there are errors in the code that is recommended. For example this following line gives an error...

crc_value = File.GetCRC(SessionVar.Expand("%AppFolder%\\setup.exe");

But replacing the missing closing bracket still gives an error...

crc_value = File.GetCRC(SessionVar.Expand("%AppFolder%\\setup.exe"));

Actually, this line is correct with the added closing bracket...

crc_value = File.GetCRC(SessionVar.Expand("%AppFolder%\\setup.exe"));

The examples given in the Help document need to be amended.
