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 "SOFTWARE\Microsoft\NET Framework Setup\NDP" */

  EnumRegKey $R1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP" $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 "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

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 '$TEMP\NetFx20SP2_x86.exe /quiet /norestart' $R1

  Delete "$TEMP\NetFx20SP2_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 "SOFTWARE\Microsoft\.NETFramework"

	StrCpy $DOTNET3 0

	DotNetStartEnum:

		EnumRegKey $DOTNET4 HKLM "$DOTNET2\policy" $DOTNET3

		StrCmp $DOTNET4 "" noDotNet dotNetFound

	dotNetFound:

		StrCpy $DOTNET5 $DOTNET4 1 0

		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 $DOTNET3 HKLM "$DOTNET2\policy\$DOTNET4" 0

		StrCmp $DOTNET3 "" noDotNet

		ReadRegStr $DOTNET5 HKLM $DOTNET2 "InstallRoot"

		StrCmp $DOTNET5 "" noDotNet

		StrCpy $DOTNET5 "$DOTNET5$DOTNET4.$DOTNET3\mscorlib.dll"

		IfFileExists $DOTNET5 yesDotNet noDotNet

	noDotNet:

		StrCmp ${DOTNETLASTFUNCTION} "INSTALL_ABORT" +1 nDN2

			MessageBox MB_YESNO|MB_ICONQUESTION \

			"You must have Microsoft .NET Framework version ${DOTNETVMAJOR}.${DOTNETVMINOR}.${DOTNETVMINORMINOR}$\nor higher installed. Install now?" \

			IDYES +2 IDNO +1

			Abort

			ExecWait '${DOTNETPATH}'

			Goto DotNetStartEnum

	nDN2:

		StrCmp ${DOTNETLASTFUNCTION} "INSTALL_NOABORT" +1 nDN3

			MessageBox MB_YESNO|MB_ICONQUESTION \

			"Microsoft .NET Framework version ${DOTNETVMAJOR}.${DOTNETVMINOR}.${DOTNETVMINORMINOR} is not installed.$\nDo so now?" \

			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:$\n$\n$\t$\tMicrosoft .NET Framework version$\n$\t$\t${DOTNETVMAJOR}.${DOTNETVMINOR}.${DOTNETVMINORMINOR} is not installed!" \

			IDOK 0

			StrCpy $DOTNET1 0

			Goto DotNetFinish

	nDN4:

		StrCmp ${DOTNETLASTFUNCTION} "ABORT" +1 nDN5

			MessageBox MB_OK|MB_ICONEXCLAMATION \

			"Error:$\n$\n$\t$\tMicrosoft .NET Framework version$\n$\t$\t${DOTNETVMAJOR}.${DOTNETVMINOR}.${DOTNETVMINORMINOR} is not installed, aborting!" \

			IDOK 0

			Abort

	nDN5:

		StrCmp ${DOTNETLASTFUNCTION} "IGNORE" +1 nDN6

			StrCpy $DOTNET1 0

			Goto DotNetFinish

	nDN6:

		MessageBox MB_OK \

		"$(^Name) Setup internal error.$\nMacro 'DotNetSearch', parameter '4'(${DOTNETLASTFUNCTION})invalid.$\nValue must be INSTALL_ABORT|INSTALL_NOABORT|WARNING|ABORT|IGNORE$\nSorry for the inconvenience.$\n$\tAborting..." \

		IDOK 0

		Abort

	yesDotNet:

		StrCpy $DOTNET1 1

	DotNetFinish:

		Pop $DOTNET6

		Pop $DOTNET5

		Pop $DOTNET4

		Pop $DOTNET3

		Pop $DOTNET2

		!define ${DOTNETOUTCOME} $DOTNET1

		Exch $DOTNET1
