在NSIS脚本内加入对.net framework和MDAC版本的判断

Share

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

1. ;判断DotNetFramework 1.1是否已经安装
   
2. xtInfoPlugin::IsDotNetFrameworkInstalled
   
3. Pop $0
   
4. ${if} $0 == true
   
5. xtInfoPlugin::GetDotNetFrameworkId
   
6. ; GetDotNetFrameworkId (id methods) return x.x and not build info
   
7. Pop $0
   
8. ${if} $0 != "1.1"
   
9. 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"
   
10. EXECWAIT '"$PLUGINSDIR\dotnetfx_cn.exe"'
    
11. ;!insertmacro DetailText "正在安装.net framework 1.1组件"
    
12. ${endif}
    
13. ${else}
    
14. 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"
    
15. EXECWAIT '"$PLUGINSDIR\dotnetfx_cn.exe"'
    
16. ;!insertmacro DetailText "正在安装.net framework 1.1组件"
    
17. ${endif}

;判断MDAC当前版本

1. Strcpy $2 "2.7"
   
2. Push $2
   
3. xtInfoPlugin::GetMDACVersion
   
4. Pop $1
   
5. Push $1
   
6. xtInfoPlugin::CompareVersion
   
7. Pop $0
   
8. ${if} $0 < 0
   
9. EXECWAIT '"$PLUGINSDIR\mdac_typ.exe"'
   
10. MessageBox MB_OK "MDAC version is OLDER than $2 (found: $1)"
    
11. ${else}
    
12. MessageBox MB_OK "MDAC version is NEWER than $2 (found: $1)"
    
13. ${endif}
    
14. over

其实在XtInfoPlugin.zip压缩包内有Example的
