Summary of the issue:

We are aware of a potential problem that you may experience with the latest updates to Office security.   When you install these updates, the Windows Update control panel returns the error 646 or 0 x 80070646.

Technical details:

Error 0 x 80070646 or 646 is a MSI installer error that won't happen when the updates are installed via the Windows Update control panel.  Workaround solution previous to solve the immediate problem requires the installation of the update to a standalone package starting from Microsoft Download Center.  We do not recommend this workaround solution.

If the Windows Installer logging is enabled, the following line must be identified as a symptom:

Error 1606. Could access the location %APPDATA%\ network

 

 

Cause:

The problem is potentially a result of an incompatible, incorrect environment (%AppData%) as variable shown below:

Solution:

1. open the registry editor.  To do this, click Start, type regedit in the search box, and then click regedit.exe in the list programs. In the user account control dialog box, click on continue.

2 go to the following registryHKEY_USERS\ keys. DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

 

3. the correct and should be the default value forAppData % USERPROFILE%\AppData\Roaming. To edit the value, double click on Appdata, then change the string in the value data field.

4. close the registry editor, and then try Windows Update again. (A restart article be required).

5. If the problem persists, repeat the steps 2 to 4 with the registry keys:

·        HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell dossiers\

·        HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell dossiers\
