The newbie and the .NET detect script
Yup, I'm new to NSIS. I find it infinitely more appealing than the windows installer, and thanks to the excellent NSIS Workbench program I had little trouble creating my setup file. However, I want to add the .NET Framework detect script to my setup so that I can give the user a URL to download the framework and abort the installation. I just finished a huge program in VB.NET, but this scripting language is boggling me.

Basically, what I need to know is how and where I should call this function in order to achieve the result I mentioned above. Anyone have some advice for me? :)

Note: I did a search of the forums on this topic, and none of them answered my question.

The forums are not the only source of information ;)

Take a look at this page:

I found that; it's the .NET detect script I was referring to. I don't understand how to implement it though.

I got it to work... sort of. I put the code near the top of the file, but it won't attempt to detect .NET until after the user clicks "Install." I want it to detect, and if it fails, to pop up a message box right before the license screen. Where should I put the code to do that?

Put the function itself anywhere in the script and then put this code where you want to check for .NET:

Call IsDotNETInstalled
Pop $0
StrCmp $0 1 +3
  MessageBox MB_OK "no .NET bla bla"
  Abort

Thanks! That was exactly what I needed to know.
