How To Successfully Fix The 339 Runtime Error

How to fix the Runtime Error 339 : Let us understand how to troubleshoot the problem first. To troubleshoot, we first need to understand the working of this error. This error is due to a file which is missing in your machine.

When you install an application, it requires a file which contains the object code required to run the file. The code is formatted in a way that it has an OCX extension.

It can be easily browsed for and opened in Microsoft Visual Studio and there you will see the object code that is written by the developers and compiled using a compiler dependent on the preference of the developer.

They are used within ActiveX forms. The behaviors that are triggered by user or program events, used typically for windows resizing and functions related to scrollbar movement are controlled properly due to the control behaviors included in the OCX files.

The runtime error which is caused in this scenario, i.e specifically the 339 runtime error which we are facing here is due to the missing files in our system and it could be due to several reasons such as the antivirus detecting it as a false positive or maybe the windows defender causing an issue with the software.

There are several times when this error may appear and the reasons may be dynamic from user to user. It may occur when you are trying to install multiple software in synergy and it may also occur when you are done with installing your applications and using them.

The main thing here is to know that it will occur when the machine you are using realizes that it cannot use the OCX files anymore and we need to check the depth where the problem is located that is the file location.
