NSIS中判断.net framework 是否安装

在网上找了几个脚本，原理都是读取注册表进行判断，都可以用。

1、CheckDotNetFramework

/*
 * Name: CheckDotNetFramework.nsh
 * Version: 0.1
 * Date: 20110720
 *
 * Author: Michael Mefford
 * Contact info: meffordm@gmail.com
 *
 * Description: NSIS header file to check a windows system for a specified .NET
 *              framework.  CheckDotNetFramework.nsh uses the NSIS stack to
 *              receive and pass values.

 *                distribution.
 *
 * Usage: Push ${DotNetFrameworkVersion}
 *        Call CheckDotNetFramework
 *        Exch $R0
 *        StrCmp $R0 "0" found not_found
 *
 * Algorithm: ...
 *
 * Input: A .NET Framework version.  This must be verbatim, including major,
 *        minor, and build version - i.e.
 *
 *          1.1.4322
 *          2.0.50727
 *          3.0
 *          3.5
 *          4
 *          4.0
 *          .
 *          .
 *          .
 *          etc.
 *
 * Output: "0" if the requested .Net Framework version IS FOUND
 *         "1" if the requested .NET Framework version IS NOT FOUND
 *
 */
 Function CheckDotNetFramework

  /* Exchange $R0 with the top of the stack to get the value passed by caller */
  Exch $R0

  /* Save other NSIS registers */
  Push $R1
  Push $R2
  Push $R3

  /* Zero out $R2 for the indexer */
  StrCpy $R3 "0"

loop:
  /* Get each sub key under "SOFTWAREMicrosoftNET Framework SetupNDP" */
  EnumRegKey $R1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDP" $R3
  StrCmp $R1 "" version_not_found  /* Requested version is not found */

  StrCpy $R2 $R1 "" 1              /* Remove "v" from subkey */
  StrCmp $R2 $R0 version_found     /* Requested version is found */

  IntOp $R3 $R3 + 1                /* Increment registry key index */
  Goto loop

/* The requested .Net Framework version WAS NOT FOUND on this system */
version_not_found:
  /* Restore the registers saved earlier */
  Pop $R3
  Pop $R2
  Pop $R1
  Pop $R0

  Push "1"  /* Put "1" on the top of the stack for caller to use */
  Goto end

/* The requested .Net Framework version WAS FOUND on this system */
version_found:
  /* Restore the registers saved earlier */
  Pop $R3
  Pop $R2
  Pop $R1
  Pop $R0

  Push "0"  /* Put "0" on the top of the stack for caller to use */
end:

FunctionEnd

使用方法: 

	;检查是否安装了3.5
  StrCpy $DotNetFrameworkVersion 3.5
	Push $DotNetFrameworkVersion
  Call CheckDotNetFramework
  Exch $R0
  ${If} $R0 == "1" ; 没有找到
     MessageBox MB_ICONSTOP|MB_OK "程序运行所必需的 Microsoft .NET Framework$DotNetFrameworkVersion 尚未安装，请先安装该组件。" IDYES
		 abort
  ${ElseIf} $R0 == "0" ; 找到指定版本的DotNetFramework
    	;检查是否安装了4.0
    	pop $DotNetFrameworkVersion
			StrCpy $DotNetFrameworkVersion 4.0
			Push $DotNetFrameworkVersion
			Call CheckDotNetFramework
  		Exch $R0
  		${If} $R0 == "1"
				MessageBox MB_ICONSTOP|MB_OK "程序运行所必需的 Microsoft .NET Framework$DotNetFrameworkVersion 尚未安装，请先安装该组件。" IDYES
				abort
		${EndIf}
  ${Endif}

　　

2、GetNetFrameworkVersion

Function GetNetFrameworkVersion
	;获取.Net Framework版本支持
	Push $1
	Push $0
	ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv4Full" "Install"
	ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv4Full" "Version"
	StrCmp $0 1 KnowNetFrameworkVersion +1
	ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.5" "Install"
	ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.5" "Version"
	StrCmp $0 1 KnowNetFrameworkVersion +1
	ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.0Setup" "InstallSuccess"
	ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.0Setup" "Version"
	StrCmp $0 1 KnowNetFrameworkVersion +1
	ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv2.0.50727" "Install"
	ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv2.0.50727" "Version"
	StrCmp $1 "" +1 +2
	StrCpy $1 "2.0.50727.832"
	StrCmp $0 1 KnowNetFrameworkVersion +1
	ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv1.1.4322" "Install"
	ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv1.1.4322" "Version"
	StrCmp $1 "" +1 +2
	StrCpy $1 "1.1.4322.573"
	StrCmp $0 1 KnowNetFrameworkVersion +1
	ReadRegDWORD $0 HKLM "SOFTWAREMicrosoft.NETFrameworkpolicyv1.0" "Install"
	ReadRegDWORD $1 HKLM "SOFTWAREMicrosoft.NETFrameworkpolicyv1.0" "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

　　

使用方法:

Call GetNetFrameworkVersion
  Pop $1
  ${If} $1 < '2.0.50727'
  MessageBox MB_OK "正在安装 .NET Framework..."
  SetDetailsPrint textonly
  DetailPrint "正在安装 .NET Framework..."
  SetDetailsPrint listonly

  SetOutPath "$TEMP"
  SetOverwrite on
  ;File "NetFx20SP2_x86.exe"
  ExecWait '$TEMPNetFx20SP2_x86.exe /quiet /norestart' $R1
  Delete "$TEMPNetFx20SP2_x86.exe"
  ${EndIf}

　　

　　

3、封装成宏

这种方式不用在脚本中添加函数代码，复用性好，有两个缺点：1）不能在一个脚本中调用多次进行多个版本的判断；2）参数中必须传入DOTNETVMAJOR DOTNETVMINOR DOTNETVMINORMINOR，如果想查4或者4.0版本，脚本中会变成4.或者4.0.，造成找不到，需要改写一下这个脚本，限于目前自己的水平，还改不了。

!macro DotNetSearch DOTNETVMAJOR DOTNETVMINOR DOTNETVMINORMINOR DOTNETLASTFUNCTION DOTNETPATH
	Var /GLOBAL DOTNET1
	Var /GLOBAL DOTNET2
	Var /GLOBAL DOTNET3
	Var /GLOBAL DOTNET4
	Var /GLOBAL DOTNET5
	Var /GLOBAL DOTNET6
	Push $DOTNET1
	Push $DOTNET2
	Push $DOTNET3
	Push $DOTNET4
	Push $DOTNET5
	Push $DOTNET6

	StrCpy $DOTNET1 "0"
	StrCpy $DOTNET2 "SOFTWAREMicrosoft.NETFramework"
	StrCpy $DOTNET3 0

	DotNetStartEnum:
		EnumRegKey $DOTNET4 HKLM "$DOTNET2policy" $DOTNET3
		
		StrCmp $DOTNET4 "" noDotNet dotNetFound

	dotNetFound:
		StrCpy $DOTNET5 $DOTNET4 1 0
		StrCmp $DOTNET5 "v" +1 goNextDotNet
		StrCpy $DOTNET5 $DOTNET4 1 1

		IntCmp $DOTNET5 ${DOTNETVMAJOR} +1 goNextDotNet yesDotNetReg
    StrCpy $DOTNET5 $DOTNET4 1 3
    
		IntCmp $DOTNET5 ${DOTNETVMINOR} +1 goNextDotNet yesDotNetReg
		StrCmp ${DOTNETVMINORMINOR} "" yesDotNetReg   yesDotNetReg
		;StrCmp ${DOTNETVMINORMINOR} "" yesDotNetReg +1
 		;Changed this line (otherwise it would not work with my setup!) - Vinz0r

	IntCmpU $DOTNET5 ${DOTNETVMINORMINOR} yesDotNetReg goNextDotNet yesDotNetReg

	goNextDotNet:
		IntOp $DOTNET3 $DOTNET3 + 1
		Goto DotNetStartEnum

	yesDotNetReg:
		EnumRegValue $DOTNET3 HKLM "$DOTNET2policy$DOTNET4" 0
		StrCmp $DOTNET3 "" noDotNet
		ReadRegStr $DOTNET5 HKLM $DOTNET2 "InstallRoot"
		StrCmp $DOTNET5 "" noDotNet
		StrCpy $DOTNET5 "$DOTNET5$DOTNET4.$DOTNET3mscorlib.dll"
		IfFileExists $DOTNET5 yesDotNet noDotNet

	noDotNet:
		StrCmp ${DOTNETLASTFUNCTION} "INSTALL_ABORT" +1 nDN2
			MessageBox MB_YESNO|MB_ICONQUESTION

			IDYES +1 IDNO +3
			ExecWait '${DOTNETPATH}'
			Goto DotNetStartEnum
			StrCpy $DOTNET1 0
			Goto DotNetFinish
	nDN3:
		StrCmp ${DOTNETLASTFUNCTION} "WARNING" +1 nDN4
			MessageBox MB_OK|MB_ICONEXCLAMATION 
			"Warning:$

			IDOK 0
			StrCpy $DOTNET1 0
			Goto DotNetFinish
	nDN4:

			IDOK 0

	nDN5:

			StrCpy $DOTNET1 0
			Goto DotNetFinish
	nDN6:

		IDOK 0
		Abort

	yesDotNet:

	DotNetFinish:
