Runtime Error 339: The Complete Repair Tutorial

If you’re an active computer user and you have a lot of programs and games installed on your Windows machine, chances are that you’ve experienced at least one or two runtime errors. Some of them appear out of the blue and disappear when you reboot your PC, but some are more persistent – they keep coming back and make using some programs (or even your computer) impossible. Runtime error 339 is one of the nasty errors but never fear, it’s not too difficult to fix – just follow the steps from this post.

Why Am I Getting the Runtime Error 339?

Most of the time, the runtime error 339 occurs when you use third-party applications that have corrupted or missing files/components. Fortunately, the error popup will tell you exactly which program and which component are causing it. Most of the time the culprit is either an .ocx or a .dll file. 

How to Fix Runtime Error 339

To repair runtime error 339, you should fix the file that’s causing the problem. It’s as simple as that. Since the error popup message tells you exactly which file is to blame, you won’t have any problems finding it. But wait and don’t run to search for the file just yet – there might be an easier fix!

Method 1: Reinstall the Program That’s Causing the Error

The easiest way to repair runtime error 339 is to reinstall the program that’s giving you the error. Here is how:

1. Make sure that you have the correct installer downloaded to your computer
2. On Windows 10, open the Start menu, click on the gear icon to go to Settings, and select Apps & Features
3. Click on the app you want to uninstall and then click on the Uninstall button that appears
   

Once the program is uninstalled, run a Windows repair tool to delete any of the remaining registry entries. This is a very important step because most of the time corrupted leftover registry settings cause the runtime error 339.

Once you’ve cleane the registry, reboot your computer and use the installer to reinstall the program.

Method 2: Register the Corrupted File Manually

If reinstalling the program didn’t work or you couldn’t do it for whatever reasons, try re-registering the corrupted file manually (only if the error message says that the file couldn’t be registered). To do that, follow these steps:

1. Press the Windows key + R, type cmd in the box that appears
2. Right-click on the Command Prompt and select Run as administrator
3. In the Command Prompt, type regsvr32 [name of the file from the error message] and press Enter
4. You will receive a message that the file got successfully registered

Method 3: Replace a Missing and Corrupted DLL or OCX File

Sometimes the runtime error 339 happens when a DLL or an OCX file disappears after an update. If that’s your case, then downloading the missing file and putting it where it belongs will solve the problem.

To do that, search a reliable DLL repository for the missing DLL, download it, and save it to your computer. When done, use Windows search to look for the file name from the error message. Go to the folder where the file is located and replace the corrupted file with the one you’ve downloaded.
