Chrome shows "no registration class" solution in Win8

Issue 1: Unable to open chrome from Taskbar and desktop shortcut, display error is not registered class

Issue 2: Cannot click Open URL from Word etc, unable to open html,htm way file, same error as no registration class

After these two errors, it's quite a hassle to open chrome and need to open it from the installation directory. This is fine, open several times a day. The most depressing is that every time you open a link from word, can not directly click Open, do not want to copy the link pasted to chrome open, it is a waste of time

Solutions
Temporary problem solving 1 : Send the Chrome_launcher.exe from the Chrome installation directory to the desktop shortcut to open Chrome, at least don't go to the installation directory and open Chrome again. finally fix issues 1 and 2:
Delete HKLM (My Computer HKCU is not) \\Software\Classes\Chrome (delete all) Update: The first time, I will delete the following or not, and then simply remove the entire Chrome, you can
\\Software\Classes\ChromeHTML\open\DelegateExecute
Resources
Http://code.google.com/p/chromium/issues/detail?id=123994Comment by [email protected], APR, 2012As another Temporary workaround You can manually delete the following registry entries in HKLM (and potentially HKCU):

\\Software\Classes\Chrome (all of it)
\\Software\Classes\ChromeHTML\open\DelegateExecute
