PROBLEM

• “When I try to open or close Gorilla, I get a runtime error 429. How do I fix this?”
• “Why do I get an error 429 when I try to edit or create a document?”

CAUSE

The problem happens because of an error in the system configuration, or a missing or damaged component. However, almost all the root causes of this error lead to the problem being some sort of problem in the Windows registry. There appear to be three common causes of this error: 

1. Incorrect permissions to change the registry. 
2. Anti-Virus programs. 
3. Registry corruption/Inaccuracies.

The recommended course of action for each of these causes is given below.

SOLUTION

Incorrect Permissions to Change the Registry

On some systems, security policies are running which prevent system files from being edited. In such instances, your local IT department will need to be consulted on a resolution (which may also involve completely uninstalling and reinstalling Microsoft Word and Gorilla).

Anti-Virus Programs

Some anti-virus programs have a feature to protect unapproved changes to the system registry. Other anti-virus programs are known to cause issues with the creation of registry entries. If this is suspected of being the case, deactivate the anti-virus program, then uninstall and reinstall both Word and Gorilla. Consult the documentation for your antivirus program for details on how to deactivate it. If the problem still occurs after you’ve reinstalled Word and Gorilla, completely uninstall your anti-virus program, then uninstall and reinstall Word and Gorilla.

Registry Corruption/Inaccuracies

This is likely the problem in most cases. There are a number of fixes specified by Microsoft (which can be viewed in the “References” section of this article). These fixes involve editing the registry and/or re-registering applications. Follow those steps only if you are very familiar with the Windows registry and its workings. If you are not comfortable with changing the registry, follow these simple steps:

1. Reboot the computer.
2. Uninstall Microsoft Office. Refer to the Office documentation for instructions on how to properly remove Office from your system.
3. Uninstall Gorilla. This is accomplished by clicking on the Start button, then selecting “Control Panel,” then selecting “Programs and Features.” Choose Gorilla from the displayed list of programs then click on the button labeled "Uninstall." From there, simply follow the on-screen prompts to remove Gorilla. Be sure to make a note of any specific settings you may need for the re-install, such as directory locations. 
4. Reboot the computer.
5. Install Microsoft Office. Refer to the Office documentation for instructions on how to properly install Office on your system.
6. Install Gorilla. Refer to the Gorilla documentation for instructions on how to properly install Gorilla on your system.

This will remove the corrupt or incorrect registry entries, and force those entries to be recreated.
