Source Insight
是一个非常好的程序开发工具，C/C++/JAVA/C#均通用，集成了IDE的多项功能，同时可以集成ClearCase组件，非常方便实用，作为一个开发人员，这个工具是基本的工具。
如果某天你发现打不开了，而且卸载再装再卸载再装，周而复始始终搞不定的话，那你就有得忙活了，如果打算重装系统，那可真就得不偿失了，悲哀啊，很不幸的我也碰到了这个问题，折腾了1天没做正事，很庆幸的是在网上居然找到了解决方法，Share给大家，
FYI。
1. Run the Uninstaller.
2 . Run regedit and delete the following 2
keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Source
Dynamics\SourceInsight
HKEY_CURRENT_USER\SOFTWARE\Source Dynamics\Source
Insight
3. Delete the folder"Program Files\Source Insight" or where ever you
installed the program.
4. Delete the folder "My Documents\Source
Insight".
5. Delete your temp files, on Windows XP it is us lly stored in
"C:\Documents and Settings\user_name\Local Settings\Temp",
where "user_name"
is your user name. DO NOT SKIPTHIS
STEP!
If you are running Vista, the temp directories are us lly
here:
C:\Users\\AppData\temp
C:\Users\Default\AppData\temp
C:\Windows\Temp
Finally,
run the installer to reinstall it.
开心吧，没得你：-）
