How to fix Windows runtime errors

Whenever you are trying to launch any software or running it for the first time, a runtime error occurs. Runtime errors in Microsoft Windows can be caused by a variety of computer issues. Sometimes, the error can be gone away by simple reopening the application, and if the error does not remove, there are various things you can do to resolve this issue.

How to fix Windows runtime errors

In order to detect and fix all Runtime errors, you can follow the procedures given below.

Tip

If you are facing problems like runtime error number and message, for instance, Runtime error 75 path/file access error; you can jump the step to the runtime error listing to see a list of runtime error codes and faults, which is given below:

Runtime Error

A runtime error can arise for a variety of reasons, on the basis on the situation:

  • The software has a bug in it.
  • There is a shortage of memory or another system resource.
  • You did something else that was not allowed or typed a foreign character into a text box.

Usually, the error displays as a little window with a description of the software that is causing the problem, as well as an error code and message. The small window, prompt might have a suggestion to contact a support team or administrator.

Some examples of Runtime errors:



If at all feasible, the best way to deal with the errors is to pay close attention to what the error says. If the error is too broad to diagnose straight away, you should go through the procedures below in order. On the other hand, if the error is particular and states anything such as Microsoft Visual C++Runtime Library, that's where you should begin.

Conflict with TSR or another running program

If you receive a runtime error warning on Windows, you can close all open apps. This will give you peace of mind that the issue isn't caused by third-party software or TSR.

If you still have troubles on Windows 95 or Windows 98 after you have successfully terminated all TSRs, look under autoexec.bat and config.sys for programs that are causing the problem. Then, with the help of renaming the files, temporarily disable these apps. For more information about this process, see the instructions below.

  1. First of all, you need to Boot to MS-DOS.
  2. Once you have arrived at the MS-DOS prompt, then you are required to type:
  1. When it is successfully completed, then reboot the computer system.

Software issue

If you are still facing the problem, the application, tool, or game that is triggering the runtime error could be malfunctioning. Verify that all available updates or patches have been obtained and applied via the developer's website.

If you found that no updates or patches are available, you need to uninstall and install again the software that is causing the problem. Also, if you are facing runtime error with your operating system, you should reinstall it.

Add-on, plug-in, or other extra software

If someone installed additional add-ons, plug-ins, or other software on own computer, these are also reason to generating different kinds of runtime errors. If there is any other software related with the program that is generating the error, you should update or uninstall it to see if it fixes the problem or not.

Restart the computer

If your computer suddenly feels much slower as compared to usual, this is the most likely cause.

The memory-related issues may be the reasons for generating some runtime errors, and restarting your computer is the quickest method to shut down everything that's currently running. This will help you to free up system resources previously occupied by the program that is causing the problem.

Computer virus

A runtime error can be caused by computer viruses and malware as they can tamper with system settings or memory. If you have installed a program on your computer that can protect your system against viruses, make sure it is up to date with the newest virus definitions.

If your system does not have any computer virus protection program, we recommend purchasing one or downloading a trial version in order to scan your computer hard drive for viruses.

Install the latest Microsoft Visual C++ Redistributable package

This is the most likely solution if your error window says something related to the Visual C++ libraries' runtime components.

Memory issue

Finally, if you are still facing problem of runtime errors and have followed all the above suggestions, you may be dealing with a hardware or memory related problem. Now, we suggest you should first contact the developer of the program that is causing the problem to see if there are any fixes available. If no solutions can be found, we suggest contacting the computer or motherboard maker for further advice or service.
