A run time error usually occurs during the execution of a program due to an inherent bug in the program’s code that was either missed or was left unresolved during the program’s development. Additionally, runtime errors may occur due to program conflicts, faulty hardware, buggy software and device drivers, malware infections, or a damaged registry. These errors may also occur if certain conditions required for a program to work are not met.

For a better understanding, let us take a look at a couple of examples of runtime errors.

Error Message: “Runtime Error ‘429’: ActiveX Component Can't Create Object”

This error usually occurs if Microsoft Scripting Engine is not on your system and a program needs to access it. You can easily resolve this issue by downloading the latest version of Microsoft Script Installer from Microsoft MSDN Web site and then installing Microsoft Script Runtime from the Microsoft Windows Script components.ActiveX problems such as these may also occur if some of the entries for required DLL files are not registered correctly in the Windows registry. To resolve this issue, you may use a good registry cleaner to scan and repair the incorrect DLL entries within the Windows registry.

Error Message: “The connection to the server has failed. Account: 'your_e-mail_account',Server:'your_POP3_server', Protocol:POP3, Port: 110, Secure(SSL): NO, Socket error: 10061, Error Number: 0x800ccc0e”

This error message is displayed when you try to use the email program on your system to send a message to a Post Office Protocol version 3 (POP3) server. Error 10061 in this case occurs when the destination server—in this case the POP3 mail server—refuses the connection request. This happens if port 25 or port 110 used to send and receive messages respectively are blocked on your computer.

To resolve this issue you need to ensure that:

* Your internet connection is working normally.
* Your e-ail program is configured correctly.
* There are no suspicious or malicious e-mail messages in your email program.
* Your computer is not infected with a virus.
* You do not have an invalid email addresses in the contact list of your email program.
* Your firewall is not blocking traffic through ports 25 and 110—default ports to send and receive email messages.

There are several tasks that you can perform to prevent runtime errors from occurring on your system. Some of these are:

* Disable unwanted programs from loading at system startup. Many of these programs are not essential for Windows to run and are required only when you use the applications to which they belong. These startup programs may cause conflicts and also slow down your system. You can disable these programs using the System Configuration Utility (msconfig) or a third-party program uninstaller tool.
* Scan and remove any virus or spyware infections using efficient and updated antivirus and antispyware tools. These malicious infections may add buggy codes to your application executables and generate runtime errors.
* Prevent runtime errors that occur due to a damaged and filled up registry by regularly cleaning the registry database with the help of a good and user-friendly registry cleaner tool.
* Check your system hardware, especially the system memory, for problems. You can use a good PC diagnostics tools to perform this task.
