NSIS：判断并安装.NET Framework 4 的例子

现在.NET开发的软件已经大行其道，但有些操作系统并不符合软件的运行要求，所以，我们需要在安装程序中进行.NET Framework的判断，如果不符合要求就进行静默安装。

 

首先，我们在Function区段进行当前.NET版本判断：

Function GetNetFrameworkVersion
  ;获取.Net Framework版本支持
  Push $1
  Push $0
  ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full""Install"
  ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full""Version"
  StrCmp $0 1 KnowNetFrameworkVersion +1
  ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5""Install"
  ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5""Version"
  StrCmp $0 1 KnowNetFrameworkVersion +1
  ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup" "InstallSuccess"
  ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup" "Version"
  StrCmp $0 1 KnowNetFrameworkVersion +1
  ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727" "Install"
  ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727" "Version"
  StrCmp $1 "" +1 +2
  StrCpy $1 "2.0.50727.832"
  StrCmp $0 1 KnowNetFrameworkVersion +1
  ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322" "Install"
  ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322" "Version"
  StrCmp $1 "" +1 +2
  StrCpy $1 "1.1.4322.573"
  StrCmp $0 1 KnowNetFrameworkVersion +1
  ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\.NETFramework\policy\v1.0""Install"
  ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\.NETFramework\policy\v1.0""Version"
  StrCmp $1 "" +1 +2
  StrCpy $1 "1.0.3705.0"
  StrCmp $0 1 KnowNetFrameworkVersion +1
  StrCpy $1 "not .NetFramework"
  KnowNetFrameworkVersion:
  Pop $0
  Exch $1
FunctionEnd

然后，在Section区段进行.NET静默安装：

Section -.NET
Call GetNetFrameworkVersion
Pop $R1
  ${If} $R1 < '4.0.30319'
  SetDetailsPrint textonly
  "正在安装 .NET Framework 4"
  SetDetailsPrint listonly
 
  SetOutPath "$TEMP"
  SetOverwrite on
  File "dotNetFx40_Full_x86_x64.exe"
  ExecWait '$TEMP\dotNetFx40_Full_x86_x64.exe /q /norestart /ChainingPackage FullX64Bootstrapper' $R1
  Delete "$TEMP\dotNetFx40_Full_x86_x64.exe"
  ${EndIf}
SectionEnd

当然，在Section区段可以做到自动在线下载而不把.NET打到安装包中，这样可以减小安装包体积，效果可参考紫辰记账本安装程序。
