Steam_API.dll is a file that's used by the “Steam API” – a central function of the Steam Application, which is used to help your computer to process the important options and information that many of today's most advanced games will use to run. We've found that Steam_API.dll is used predominantly to help connect games such as “Call Of Duty Modern Warfare 2,” “Just Cause 2” and a number of other applications to the Steam servers. If you're a gamer, you'll know the value of Steam to any game, making it vital that you're able to repair the various errors and problems that it might have.

The problem that Steam_API.dll has is that your computer is unable to process the settings that it needs to run this file. This can either be down to the likes of Steam_API having some sort of problems itself, or Windows having issues with its important options and settings. To fix this problem, we recommend fixing the various problems that Windows might have by downloading a tool to fix the errors of steam_api.dll, and then repairing them. Here are the steps of how to fix this error:

  • Replace Steam_API on your PC
  • Re-Install Steam itself
  • Clean out the “registry” of your system

How To Fix Steam_API.dll Errors

STEP 1 – Re-Install Steam and Games Causing The Error

The initial step should be to re-install the Steam application on your PC. This can be done by clicking onto “Start” > “Control Panel” > Add / Remove Programs, and then picking “Steam;” and any other software that could be causing problems. This will allow you to remove them from your system, whereby you'll then be able to re-install them after a quick restart of your system. This should ensure the files the program will be using to run will help your PC to run much smoother.

STEP 2 – Manually Replace Steam_API

You should then replace steam_api. This might sound drastic, but it's actually very easy to do – just by clicking onto a website which allows the download of Steam_API, installing it onto your system. After that, you should then click onto C:/Windows/System32 and rename the current Steam_API file to “Steam_APIOLD.dll”. This provides a backup of the file in case something should go wrong. After that, you should place the Steam_API.dll file into that exact folder, ensuring that it's able to process the various settings that Windows needs to run again.

STEP 3 – Clean Out The Registry Of Your PC

You need to clean out the registry because it's a huge cause of the Steam_API.dll error. The registry is what Windows uses to help it process a number of important settings and options. Although it's used continually to help load up everything from your most recent emails to your desktop wallpaper settings, it's often being damaged – leading your computer to run much less reliably and with problems as a result. In order to repair many of the problems that a computer may have, it's recommended that you use a registry cleaner to scan through your system and fix the various issues on there.

We recommend the use of a program called “Frontline Registry Cleaner” to fix the errors that Steam_API.dll has. This is a popular registry repair tool, that's been created to help you remove the various problems that your system may have inside.
