Error 1406. Setup cannot write the value mlcfg32.cpl

Question

Hi to all. I am attempting to upgrade Office 2007 Standard to Office 2013 Pro. I have used the OCT tool to create a custom MSP. On some machine the upgrade fails. It is always the same error (see below).

12.Click Advanced.
13.Click the Permissions tab.

Answer 1

Hi Phil,
Thank you for your questions. Have you uninstalled Office 2007 from the machine before the Office 2013 installation?
I believe you've already seen this KB article before, the steps above are quoted from it:
http://support.microsoft.com/kb/838687
As can been seen from the article, the steps above are specific to Method 4. There are three other Methods mentioned in the article, have you ever tried them? If not yet, I would suggest you to have a try:
Method 1: Set the permission for the Everyone group of the registry subkeys that are listed in the error message to Full Control.
Method 2: Disable the third-party application.
Method 3: Try the installation again in
Let me know if the issue persists after the steps above, we'll take a further look then.

It's recommended to download and install
Configuration Analyzer Tool (OffCAT), which is developed by Microsoft Support teams. Once the tool is installed, you can run it at any time to scan for hundreds of known issues in Office
