官方解决方案
For Windows Vista users:
If the Flash uninstall / reinstall does not work this maybe due to a Microsoft Windows Vista permissions issue.
Please use the Windows button at the bottom left then the search function:
-Go to: C:\Windows\System32\Macromed\Flash\.
-Right-click on the following file: FlashUtil10b.exe or FlashUtil10e.exe.
-Select "Run as Administrator" and install the update..
-Restart your computer.
大意:如果你是windows Vista(或win7)用户,打开 C:\Windows\System32\Macromed\Flash\. ,找到FlashUtil10b.exe or FlashUtil10e.exe文件,右键打开,以管理员身份运行,好了重启电脑就行了
