Unable to complete Office 2010 Installation

Asked By 10 points N/A Posted on -


I currently have Microsoft Office 2007 installed on my personal computer. I recently purchased Microsoft Office 2010 and tried installing it on my personal computer ,but was unable to complete the installation.

I get the following error message during the installation.

"Error 1406. Setup cannot write the value to the registry key."

Then the installation is canceled. Does anyone know what this error message means. I did uninstall Microsoft Office 2007 on my computer ,so there should be no conflicting registry entries. 

I tried the installation several times using several installation medias, but still get the same error message. 

I also restarted my computer several times, but it did not help.

Dear Christina Tate,

Set the permission for the group registration all subkeys that appear in the error message for total control. To do so,

  1. Click Start, click Run, type regedit in the Open box and then click OK.
  2. In Registry Editor, locate and click the subkey that appears in the error message.
  3. In the Edit menu, click Permissions.
  4. In group or user names, click around the world.

You must add the group if you are not available all. To do this, follow these steps:

  • With the permission of the Office of dialog box, click Add.
  • In the dialog box select users, computers, or groups, click Advanced.
  • In the dialog box select users, computers, or groups, click Find Now.
  • Under the name (RDN), click all over the world and then click OK.
  • In the dialog box select users, computers, or groups, click Ok.
  • In permissions for all, click to select the Full Control check box.
  • Click Ok and quite the registry editor.

I hope that this will work
