在NSIS脚本内加入对.net framework和MDAC版本的判断

首先到NSIS官网上下载一个插件，名：XtInfoPlugin.zip，链接地址：http://nsis.sourceforge.net/mediawiki/images/d/de/XtInfoPlugin.zip

将插件：xtInfoPlugin.dll复制到NSIS安装目录..\NSIS\Plugins下

在脚本内添加一句

如：!addplugindir "C:\Program Files\NSIS\Plugins"

然后在Funtion.onInit内

;判断DotNetFramework 1.1是否已经安装

xtInfoPlugin::IsDotNetFrameworkInstalled

Pop $0

${if} $0 == true

xtInfoPlugin::GetDotNetFrameworkId

; GetDotNetFrameworkId (id methods) return x.x and not build info

Pop $0

${if} $0 != "1.1"

Messagebox MB_OK "系统检测到您计算机上的DotNetFramework版本低于1.1，点击[确定]安装"

EXECWAIT '"$PLUGINSDIR\dotnetfx_cn.exe"'

;!insertmacro DetailText "正在安装.net framework 1.1组件"

${endif}

${else}

Messagebox MB_OK "系统检测到您计算机上没有安装DotNetFramework1.1，点击[确定]安装"

EXECWAIT '"$PLUGINSDIR\dotnetfx_cn.exe"'

;!insertmacro DetailText "正在安装.net framework 1.1组件"

${endif}

;判断MDAC当前版本

Strcpy $2 "2.7"

Push $2

xtInfoPlugin::GetMDACVersion

Pop $1

Push $1

xtInfoPlugin::CompareVersion

Pop $0

${if} $0 < 0

EXECWAIT '"$PLUGINSDIR\mdac_typ.exe"'

MessageBox MB_OK "MDAC version is OLDER than $2 (found: $1)"

${else}

MessageBox MB_OK "MDAC version is NEWER than $2 (found: $1)"

${endif}

over

其实在XtInfoPlugin.zip压缩包内有Example的
