.NET 3.5 SP1 with InstallScript

[Guido_Herrling]

Hello.

In our company we use the InstallScript (not InstallScript MSI Project) technology for our setups. Now we have to setup a new setup for our next geneneration Software. This software needs .NET 3.5 SP1.
I didn't find any option to check for .NET or better to install .NET. In any other setuptype this can be done by "Redistributables". Is there any way to do it in plain InstallScript Projects ? If not, how different is the paradigm for InstallScript MSI Projects ?

I believe the Is() function has support for checking installed versions of .NET, and LaunchApplication() can certainly run Microsoft's .NET redistributables. I'm not aware of any pure InstallScript pre-built options for .NET 3.5 SP1 at this time.

Here's what we did since InstallShield does not handle checking and installing prerequisites for updates (v1 required .net 2.0, v2 requires .net 3.5); it only handles for new installs. Indenting is probably messed up,,,

and these are functions we found we needed. IS adds the iversion registry entry after OnMoveData(), and if you abort the install here (we called these from OnMoving(), the next execution thinks this version was already installed, when infact it hadn't) DeleteRegistryVersionAfterAbort();


and we wrote a routine to ask if the user wanted this prereq installed:
AskInstallDotNet3_5SP1();
