Installing the Microsoft .NET Framework

Author: zimsms (talk, contrib)

Description

I have supplied the following since most people installing the .NET Framework, only choose to install the English version, which may be incorrect for their end users machine. This also contains the proper error handling, which most installs do not use. This 'Template' can be used for pretty much any Microsoft download with a few modifications. I have cut most of the 'extra' languages out to keep the example simple. THIS IS NOT A COMPLETE SCRIPT, IT IS INTENDED TO ASSIST THOSE REQUIRING THE INSTALLATION OF THE .NET FRAMEWORK FOR A MULTI-LANGUAGE INSTALL.

This requires some setup in .OnInit:

Function .onInit
  StrCpy $LANGUAGE_DLL_TITLE "Installer Language"
  StrCpy $LANGUAGE_DLL_INFO "Please select a language:"
  StrCpy $URL_DOTNET "${URL_DOTNET_1033}"
  StrCpy $OSLANGUAGE "1033"
 
; Insert other Language Blocks Here
 
  !define MUI_LANGDLL_WINDOWTITLE "$LANGUAGE_DLL_TITLE"
  !define MUI_LANGDLL_INFO "$LANGUAGE_DLL_INFO"
  !insertmacro MUI_LANGDLL_DISPLAY
  !undef MUI_LANGDLL_WINDOWTITLE
  !undef MUI_LANGDLL_INFO
  InitPluginsDir
  SetOutPath "$PLUGINSDIR"
  File "Common\Plugins\*.*"
  File /r "${NSISDIR}\Plugins\*.*"
FunctionEnd

I test for IsDotNetInstalled by defining a custom function overriding GUI Init, and set the section selection accordingly. Hopefully this was of use to you. Cheers!
