DotNET

Overview

DotNET is a macro written to aid in the deployment of .NET Framework 2.0-based applications using NSIS.

What it does

  1. Checks the version of the .NET framework on the end-user's computer.
  2. Prompts them with a yes/no dialog if their version is different than the defined DOTNET_VERSION in the installer's main script.
  3. If they press yes, the installer downloads the latest .NET Framework 2.0 installer and runs it.

Limitations

  • Only works for .NET Framework 3.5, not 1.0 or 1.1 or 2.5 or 3.0 ...
  • See talk page for 3.5 hack up!
  • Won't work on XP 64 (as downloads the 32 bit installer by default)
  • High risk of causing a false positive for "generic downloader trojan" in Kasperky antivirus software. No matter if you use inetc or NSISDL (verified in production with 1000+ downloads 2011-09-09).

Usage

Including the Script

Save the Script contents as DotNET.nsh in the same folder as your main script, and put line in your main script like this: 

!include "DotNET.nsh"

DotNet.nsh uses the ${if} function of LogicLib, so you also have to include it in your script: 

!include LogicLib.nsh

Required Variables

Define the variable DOTNET_VERSION as the full or partial version of .NET Framework your app requires, like so: 

!define DOTNET_VERSION "2.0.50727"

or 

!define DOTNET_VERSION "2.0.5"

or 

!define DOTNET_VERSION "2"

Using the Script

Insert the macro CheckDotNET into your script inside the first required section of the installer: 

Section "Main Section (Required)"
	SectionIn RO
 
	!insertmacro CheckDotNET ${DOTNET_VERSION}
 
	#Files here
SectionEnd

MSI Check Overview

Added check for MSI3. MSI check code based on [1]

What it does

  1. Checks the version of the MSI on the end-user's computer.
  2. Prompts them with a yes/no dialog if their version is lower than 3.
  3. If they press yes, the installer downloads the latest MSI3.1 installer and runs it.
  4. Checks the version of the .NET framework on the end-user's computer.
  5. Prompts them with a yes/no dialog if their version is different than the defined DOTNET_VERSION in the installer's main script.
  6. If they press yes, the installer downloads the latest .NET Framework 2.0 installer and runs it.
