1、删除旧的配置文件，比如C:documents and SettingsXXXLocal SettingsApplication DataGoogle文件夹(红色部分是你的计算机名)2、彻底清理注册表，删除chrome的相关文件，复制http://www.google.com/support/chrome/bin/resource/remove.txt里的内容到记事本，保存为.reg文件，双击运行！内容如下：Windows Registry Editor Version 5.00; WARNING, this file will remove Google Chrome registry entries ; from your Windows Registry. Consider backing up your registry before; using this file: http://support.microsoft.com/kb/322756; To run this file, save it as 'remove.reg' on your desktop and double-click it.[-HKEY_LOCAL_MACHINESOFTWAREClassesChromeHTML] [-HKEY_LOCAL_MACHINESOFTWAREClientsStartMenuInternetchrome.exe] [HKEY_LOCAL_MACHINESOFTWARERegisteredApplications]"Chrome"=-[-HKEY_CURRENT_USERSOFTWAREClassesChromeHTML] [-HKEY_CURRENT_USERSOFTWAREClientsStartMenuInternetchrome.exe] [HKEY_CURRENT_USERSOFTWARERegisteredApplications]"Chrome"=-[-HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionUninstallChrome][-HKEY_CURRENT_USERSoftwareGoogleUpdateClients{8A69D345-D564-463c-AFF1-A69D9E530F96}][-HKEY_CURRENT_USERSoftwareGoogleUpdateClientState{8A69D345-D564-463c-AFF1-A69D9E530F96}][-HKEY_CURRENT_USERSoftwareGoogleUpdateClients{00058422-BABE-4310-9B8B-B8DEB5D0B68A}][-HKEY_CURRENT_USERSoftwareGoogleUpdateClientState{00058422-BABE-4310-9B8B-B8DEB5D0B68A}][-HKEY_LOCAL_MACHINESOFTWAREGoogleUpdateClientStateMedium{8A69D345-D564-463c-AFF1-A69D9E530F96}][-HKEY_LOCAL_MACHINESOFTWAREGoogleUpdateClients{8A69D345-D564-463c-AFF1-A69D9E530F96}][-HKEY_LOCAL_MACHINESOFTWAREGoogleUpdateClientState{8A69D345-D564-463c-AFF1-A69D9E530F96}][-HKEY_LOCAL_MACHINESOFTWAREWow6432NodeGoogleUpdateClients{8A69D345-D564-463c-AFF1-A69D9E530F96}]3、重启电脑，安装已下载的离线安装包Chrome！注意，如果以上方法仍旧不可行。1、请把C:Program FilesGoogle文件夹手动删除。

2、使用第三方工具RegWorkshop,检索关键字“Google”和“Chrome”，删除关联的注册表信息。

3、重启电脑，再试一次。
