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 */

/* 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

yesDotNet:
