Executing an EXE from within installer BEFORE installing

Hi

I am trying to find out how to call an EXE within my installation before the actual main installation starts.
The EXE captures detailed registration information which automatically uploads the information to our web servers.

I have done this with commercial MSI installers in the past but have no idea how to achieve it in NSIS.

Can anyone please give me a point in the right direction?

Thanks 🙂

1. See .onInit
2. See ExecWait, ExecShell, Exec
3. See Inetc.

or

Create your page, with InstallOptions. 🙂

Thanks will try that!
