Error 1402 when uninstalling Office 2007

Gata · 08 Jul 2010

Hello, SevenForums.

Recently, I had acquired my copy of Microsoft Office Professional 2010, and I installed it without removing Office 2007 (i believe this is the problem and that I should have made a separate directory for Office 2010 when I installed it).

Recently, when running any Office 2007 application, it has always needed to configure it, before going on to tell me that Microsoft Office _____ was not installed for the current user.

So I tried uninstalling it.
However, it then gave me this error:

Microsoft Office Professional Plus 2007 uninstall did not complete successfully.
Error 1402.Setup cannot open the registry key
UNKNOWN\Components\DA42BC89BF2F5BD0AF18C3B9B1A1EE8\000021191100000000000F01FEC. Verify that you have sufficient permissions to access the registry or contact Microsoft Product Support Services for assistance. For information about how to contact PSS, see C:\Users\Myname\AppData\Local\Temp\Setup000005ec\PSS10R.CHM

What do I do?

Should I uninstall Office 2010, then try uninstalling Office 2007, then reinstall Office 2007, before reinstalling Office 2010 in a different directory?

Or is there any way I could force install?

Could it be a problem with the registry?

Or what?

Hi !! Welcome to SF !!

I have seen similar issue with another software but the fix is kind of same. This happens when you don't have enough permission to those Registry Key you have mentioned in the error message. It quiet lengthy fix

First we have to Enable Build-in Administrator

Then Login under Build in administrator

Although, the GUIDS that appear in the actual error message which are beneath the parent key, are random. Please use the following steps to work around this issue:

1. Click Start under search type regedit.
2. Click Edit and select Find. The Find dialog box appears.
3. In the Find What field, type the GUID that was referenced in the error message and click Find Next.

Once located from the search, give the registry key adequate permissions:

1. Right-click on the key and select Properties. Click on the Security tab.
2. Click the Advanced button, then select the Owner tab.
3. Under the Owner tab, highlight the account your are currently signed into Windows as,
check the "Replace owner on subcontainers and objects" box, click Apply, then click OK.

4. Close the Properties screen, then reopen it (see Step a).
5. Click the Security tab, highlight User account you selected to be the Owner in Step d and click the Advanced button and then Edit on the Permissions tab.

6. Check all boxes under the Allow column. Click Apply, then click OK.

7. Close out of the registry and attempt the installation again.

Note: If you recieve the same error, but referencing another GUID after giving permission to the initial GUID that prompted the error, repeat the above section to search the registry and give the appropriate permission.

Hope this helps,
Captain
