setup wizard (Howto)

[NightHog]

Hi,

I am creating setup wizard project to do the following:

a. Check whether dotnet framework is installed,.
b. If not install it and continue with the main installation.

However, i am unable to do this, I have to execute setup.exe again to
install my application after dotnet is installation is done.
How do I do this automation?

Another thing, my setup.ini looks like this:

[MSILoader]
MSIFileName=MyApplication.msi
[FXSection]
SupportedRuntimes=1.1.4322
InstallUrl=dotnetfx.exe
Message=1.1.4322
UseDefaultMessage=1

Is this the right way to this?
dotnetfx.exe is a standalone file which need to be in the same location as
my setup.exe, is there a way I can package these into my setup.exe
altogther?

Thanks.
