Hi, I need to call an encrypting function in the .NET framework and was wondering if there was an easy way to do this.

Since the app we are installing requires the .NET framework I can be sure it is on the machine already, and if I could call it from a custom action it would make my life much easier.

I know I can wrap it in my own dll and use that as a support file, but I would much rather not have to do this at all. I only need to call 1 function in the .NET framework and it seems overkill to have to write a straight wrapper dll.

Thanks!

MSI can call installer classes in a .NET assembly

Thanks Stefan!

All I need now is how. Do you mean adding it as a normal custom action that calls a dll? Will Installshield automatically find the .NET dll?

I will try this, I have looked in the help and can't find anything talking about calling .NET classes. When you say it can call "installer" classes I don't understand...

Which InstallShield version are you using? I think this was added in Developer 8 (or 7 maybe?)

I'm using IS DevStudio9 SP1.

If your assembly includes a Installer class derived from System.Configuration.Install.Installer you can set the ".NET Installer Class" option to yes in the component properties.
