NSIS安裝與.NET 4.5

Question

我一些代碼段後，我爲NSIS檢測並有條件地運行.NET 4.5安裝程序

這個答案 - NSIS Installer with .NET 4.0 - 太天真僅檢查註冊表項的presense（不是值）不會區分4.0和4.5

Answer 1

您不應該檢查確切的版本號。這將在未來發生變化（如4.0> 4.5）。請使用deployment guide中的代碼。

除此之外，你應該嘗試處理從.Net 4.5重新啓動。

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}
