Error 1406: Setup cannot write the value to the registry key

Error 1406: Setup cannot write the value to the registry key

Hello,

This error looks really horrible. Registry key is a much protected data area that is being protected with administrative privilege. It is hardly editable/readable to programs that don’t have administrative privilege to complete their tasks.

Firstly, exit the setup, right-click on the setup launcher, select “Run as administrator”. This will give the application administrative right to read and write data to disk and registry.

You can also take the help of this Microsoft Fixit.

Here is also another way to fix this.

1. Open Windows Explorer.
2. Press “Alt” button.
3. From the top ribbon that appeared, click Tools >> Folder options….
4. Open “View” tab.
5. Find out the following lines:

“Show hidden files, folders, and drives.” = Select this item.

“Hide extensions for known file types” = Uncheck

“Hide protected operating system file (Recommended)” = Uncheck

6. Press “Apply”.
7. Go to “C:UsersAll UsersMicrosoftOfficeData”.
8. Find out the following file according to your MS Office product:
   For MS Office 2007: Opa12.dat

For MS Office 2003: Data.dat

9. Right-click on the file >> select “Properties”.
10. Go to Security tab >> Advanced >> “Permissions” tab.
11. Select “Everyone” in the “Permission entries” >> click “Edit”.
12. Check “Full Control” checkbox.
13. Click “OK” continuously to get out of the settings.

Now your problem should have gone forever.
