Talk:DotNET

In the script for the first example the pops for the register restore are in the wrong order.

--PLJ-- Some day someone will work out how to:
a) Detect .Net 3.5
b) Install into it!
If anyone knows how, document it, please.

Installing on non English systems

This script fails on Japanese windows XP with the error:

"Command line option syntax error. Type Command /? for Help"

The fix is simple: Encase the path in ExecWait with inverted commas '"'.

I.e. change to:

ExecWait '"$TEMP\dotnetfx.exe" /q /c:"install /q"'

DotNET3Point5

I hacked this up for 3.5

# DotNET version checking macro.
# Written by AnarkiNet(AnarkiNet@gmail.com) originally, modified by eyal0 (for use in http://www.sourceforge.net/projects/itwister), hacked up by PSIMS APS MEDILINK 20090703 for dotnet 3.5
# Downloads and runs the Microsoft .NET Framework version 2.0 Redistributable and runs it if the user does not have the correct version.
# To use, call the macro with a string:
# 'CheckDotNET3Point5'
# All register variables are saved and restored by CheckDotNet
# No output
 
!macro CheckDotNET3Point5

Using inetc plug-in for download

I prefer the Inetc plug-in because it has a better proxy support than NSISdl.

Just download the Inetc plug-in ZIP file, extract the inetc.dll and put it into your plugin folder.

Than replace these lines within DotNET.nsh

DownloadDotNET:
  DetailPrint "Beginning download of latest .NET Framework version."
  NSISDL::download ${DOTNET_URL} "$TEMP\dotnetfx.exe"
  DetailPrint "Completed download."
  Pop $0
  ${If} $0 == "cancel"
    MessageBox MB_YESNO|MB_ICONEXCLAMATION \
    "Download cancelled.  Continue Installation?" \
    IDYES NewDotNET IDNO GiveUpDotNET
  ${ElseIf} $0 != "success"
    MessageBox MB_YESNO|MB_ICONEXCLAMATION \
    "Download failed:$\n$0$\n$\nContinue Installation?" \
    IDYES NewDotNET IDNO GiveUpDotNET
  ${EndIf}

with those lines

DownloadDotNET:
  DetailPrint "Beginning download of latest .NET Framework version."
  inetc::get "${DOTNET_URL}" "$TEMP\dotnetfx.exe" "/end"
  DetailPrint "Completed download."
  Pop $0
  ${If} $0 == "Cancelled"
    MessageBox MB_YESNO|MB_ICONEXCLAMATION \
    "Download cancelled.  Continue Installation?" \
    IDYES NewDotNET IDNO GiveUpDotNET
  ${ElseIf} $0 != "OK"
    MessageBox MB_YESNO|MB_ICONEXCLAMATION \
    "Download failed:$\n$0$\n$\nContinue Installation?" \
    IDYES NewDotNET IDNO GiveUpDotNET
  ${EndIf}
