How To Successfully Fix The 339 Runtime Error

RunTime Error 339

Runtime Error 339 is caused when an .OCX file (generally the dunzip32.ocx) file is missing from a software application that you are trying to install on your computer. The 339 error won’t necessarily appear during the installation of the application,  but may occur when you try and use the program for the first time – when your PC realizes that it cannot use the .ocx file it requires. To fix this,  you should look to repair the damaged / missing file at the root of the problem.

What Causes The Runtime 339 Error?

This error normally shows in this format:

“Runtime error 339: Component duzocx32.ocx is not correctly registered or file is missing”

The above error is caused when a .ocx / .dll file is missing from the installation of a program on your PC. In most instances, the file at the root of this problem is dunzip32.dll, which is used by Windows.

Like most run time errors, 339 generally occurs when a link in the sequence of processes that enables the program to launch is missing, interrupted or corrupted. The value in theses sequences consist of numerous data files and system files that are required to ensure the integrity of the application launch. In order for the launch to be successful, all processes involved must work together in perfect harmony. The “RunTime” error is simply a problem which occurs with the files / data / settings that need to be used to help a program run, which means that to stop the error occurring, you need to repair the problems causing it.

The best way to resolve the runtime 339 error is to unregister the duzocx32.ocx file, which in most cases is probably damaged, and delete it. Because this file is needed by the dunzip32.dll file then deleting it will stop the need for it.

This process will unregister and delete the damaged duzocx32.ocx file.

  • Select Local Hard Drives in the look and drop-down list, and click the search button.
  • Right click the duzocx32.ocx that appears in the right-pane and click Delete.

Step 3 – Clean Out The Registry

Registry cleaners can play a very important role in how well Windows operates, and can help stop the Runtime 339 error. The registry is basically a central database which stores vital settings and information for your system, allowing Windows to remember a huge number of details for your PC. Unfortunately, the registry is also prone to becoming corrupt, leaving your system running extremely slowly and unreliably. To fix this problem, you should use a ‘registry cleaner’ to scan through your registry and repair any of the damaged parts of it that are causing your computer to run extremely slowly or with errors.
