Error 1402 : While Installing Microsoft Office 2010 Professional Plus

Asked By 0 points N/A Posted on -


I am attempting to install recently purchased download version of Microsoft Office 2010 Professional Plus. Each time I get the following error message when I enter the key (#) for the installation process but the setup can’t open the registry key. Can you provide me the proper details of installation and how to fix this issue? Any suggestion would be greatly appreciated.

Hi William,
The error occurs due to lack of permissions to modify the sections of registry key, required to perform the action.
The solution for the error is:
1)  Log into the system by using the Administrator account
2)  Start 'Microsoft Windows Explorer’
3)  On ‘Tools’ menu, Click ‘Folders’ option
4)  Click ‘View’ tab
5)  Under ‘Hidden Files and Folders’, select ‘Files and Folders’
6)  Click to clear ‘Hide extensions for known file types’,Click ‘OK’
7)  Open the folder containing C:Documents and SettingsAll UsersApplicationDataMicrosoftOfficeData
