NSIS安装与.NET 4.5

Question

我一些代码段后，我为NSIS检测并有条件地运行.NET 4.5安装程序

这个答案 - NSIS Installer with .NET 4.0 - 太天真仅检查注册表项的presense（不是值）不会区分4.0和4.5

Answer 1

您不应该检查确切的版本号。这将在未来发生变化（如4.0> 4.5）。请使用deployment guide中的代码。

除此之外，你应该尝试处理从.Net 4.5重新启动。

Function CheckAndInstallDotNet

    ClearErrors 
    ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" "Release" 

    IfErrors NotDetected 

    ${If} $0 >= 378389 

     DetailPrint "Microsoft .NET Framework 4.5 is installed ($0)" 
    ${Else} 
    NotDetected: 
     DetailPrint "Installing Microsoft .NET Framework 4.5" 
     SetDetailsPrint listonly 
     ExecWait '"$INSTDIR\Tools\dotNetFx45_Full_setup.exe" /passive /norestart' $0 
     ${If} $0 == 3010 
     ${OrIf} $0 == 1641 
      DetailPrint "Microsoft .NET Framework 4.5 installer requested reboot" 
      SetRebootFlag true 
     ${EndIf} 
     SetDetailsPrint lastused 
     DetailPrint "Microsoft .NET Framework 4.5 installer returned $0" 
    ${EndIf}
