首先，去vs2010扩展网站下载visual assist for visual studio 2010
http://visualstudiogallery.msdn.microsoft.com/D6678A1F-C700-4532-8C5E-A799D875063D
下载会得到VA_X_Setup1819.vsix文件。
双击运行。
VC2010的破解方法
破解方法：
去这个网站下载破解文件 http://piggyxp.download.csdn.net/。
然后找到目录:
使用2010的朋友要特别注意，因为2010的Visual Assist X是使用Extension的方式安装的，所以你得到这个路径去破解：
Windows7
C:/Users/用户名/AppData/Local/Microsoft/VisualStudio/10.0/Extensions/Whole Tomato Software/Visual Assist X/10.7.1906.0
XP:
C:/Documents and Settings/用户名/Local Settings/Application Data/Microsoft/VisualStudio /10.0/Extensions/Whole Tomato Software/Visual Assist X/10.7.1906.0
覆盖掉文件VA_X.dll文件即可.
怎么查看是否注册，点击[visual assist x]->about，如果没有看到enter register code,则说明已经注册。

启动vs2010会有提示：
Welcome to Visual Assist X!
Visual Assist X parses all of your header and source files the first time you open a project in order to give you meaningful assistance as you edit. Parsing begins after you close these tips and open a project.
Visual Assist X comes alive when the parsing completes, and it stores parsed information so future startups occur at normal speed.
While Visual Assist X is parsing, open the Visual Assist X Options Dialog to customize the experience. Make high level changes using the initial Options page or delve into the Advanced pages for finer control of individual features.
Enjoy your trial.
禁用visual assist
在VS2008或VS2010菜单栏中选择“VassistX”选项卡，找到“Enable/Disable Visual Assist X”选项，
点击即可禁用。http://www.cnblogs.com/babycool/archive/2011/08/13/2136895.html
我最开始是从官网下载的exe文件。http://www.wholetomato.com/downloads/downloadTrial.asp。这是for all ides.
安装后再运行vs2010报错。报错的问题和这个帖子一样。http://forums.wholetomato.com/forum/topic.asp?TOPIC_ID=10457
