NSIS脚本学习：判断版本并安装.NET Framework运行环境

时间：2025-04-20 11:51:52

前言

目前开发的程序以基于.net的应用程序为主，程序开发好后，需要进行安装包的生成，及setup文件的生成。
常见的是NSIS工具，之前一直用的单文件打包工具，不适合将运行环境加进去，因此开始使用更高版本的NSIS 3.06。

关于判断.NET Framework运行环境 （离线安装）

  1. 首先添加头文件： 用来版本比较
!include ""
  1. 添加 GetNetFrameworkVersion 函数，这里给出完整函数代码：
Function GetNetFrameworkVersion
	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\v4\Client" "Install"
	ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Client" "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
  1. 最后，在Section区段进行比较版本号并静默安装.NET：
Section -.NET
	Call GetNetFrameworkVersion
	Pop $R1
	${VersionCompare} "4.0.30319" "$R1" $R2
	${If} $R2 == 1
 		SetDetailsPrint textonly
 		DetailPrint "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'
 		Delete "$TEMP\dotNetFx40_Full_x86_x64.exe"
	${EndIf}
SectionEnd

这里的dotNetFx40_Full_x86_x64.exe放在脚本路径下就可以，编译会自动打包到一个文件里面去。

附录

最后附上一个比较版本号的section：

Section - "比较版本号"
	Call GetNetFrameworkVersion
	Pop $R1
	${VersionCompare} "4.0.30319" "$R1" $R2
	${If} $R2 == 0
		MessageBox MB_OK "版本相同($R1)"
	${ElseIf} $R2 == 1
		MessageBox MB_OK "已安装版本低($R1)"
	${ElseIf} $R2 == 2
		MessageBox MB_OK "已安装版本高($R1)"
	${EndIf}
SectionEnd
