Common steamui errors

What is this error?

The file SteamUI.dll is a Dynamic Link Library (DLL). Dynamic Link Library files are a “handbook” for executable files to obey. These files were made so that numerous apps may share the same dll file, saving important memory and allowing your computer to function faster.

Regrettably, the same properties that make DLL files so useful and effective also make them particularly vulnerable to errors. For example, a “runtime” error message can be generated when something goes wrong with a shared DLL file. This is when they become missing or corrupted in some manner. The following are some of the most prevalent SteamUI errors:

  • Cannot find [PATH]\steamui.dll
  • The file steamui_dll is missing
  • Steamui.dll is not loading 
  • This application failed to start because steamui.dll was not found. 
  • Cannot start [APPLICATION]. A required component is missing: steamui dll. Please install [APPLICATION] again.

When does it occur?

When Windows starts, when an application is opened, when a program is running, when a program is closed, or at practically any other point during a Windows session, a steamui.dll problem may arise.

No matter the occurrence of the error, in troubleshooting, it’s an important step to recognize the time. This is so that you can see when the steamui.dll error is happening. In addition, knowing how to identify how to fix the problem requires one to know the context.

What causes it?

Steamui.dll issues are caused by conditions that result in the steamui DLL file being removed or corrupted. Steamui.dll failures can sometimes suggest a registry issue, a virus or spyware issue, or even a hardware failure.

How to fix it?

To resolve the numerous causes of problems that lead to this error, follow the steps below:

  1. Obtain the file from the Recycle Bin and restore it. The most common cause of a lost steamui.dll file is that you accidentally removed it. If you fear you’ve mistakenly deleted this DLL file but have already emptied the Recycle Bin, a free file recovery program may be able to help you retrieve it.
  2. To force Steam to replace the steamui.dll or libswscale-3.dll file, delete it. You may need to delete the “beta” folder instead. If the steamui.dll or libswscale-3.dll files are still available at the root of Steam’s installation directory, usually C: Program Files (x86) Steam and they haven’t been destroyed, try deleting them. Then, open Steam and force the software to update, replacing the DLL file with a new one. If that doesn’t help, or if you’re using a beta version of Steam, removing the C: Program Files (x86) Steam/package/beta folder may be the fastest way to fix the DLL problem.
  3. To fix corrupt files and maybe return them to functioning order, you can refresh your steam files.
  4. Using the internet directions, uninstall and then reinstall Steam. An error with the steamui.dll file can happen after Steam upgrades or due to other issues. In that case, reinstalling is the ideal route you need to go for.
  5. If the preceding troubleshooting advice is ineffective, a startup repair or repair should return all Windows DLL files to their previous operating state. You may require some of them for the steamui DLL file to function properly.
  6. Scan your entire system for viruses and malware. Some steamui.dll issues are caused by a virus or other malware attack that has corrupted the DLL file on your computer. It’s also understandable that the error you see now is caused by a malicious application impersonating the file.

Is setamui safe? Is it malware?

SteamUI.dll should not harm your PC, so the answer is no. However, unlike executable programs like those with the EXE extension, you cannot run DLL files directly; instead, they must be called by another program that has already run. 

On the other hand, DLLs have the same structure as EXEs, and some even have the.EXE extension. Thus, DLL files are beneficial because they allow a program to break down its various components into distinct modules, which may be added or removed to include or exclude specific features.

However, the.dll file may be harmful if it is associated with an executable designed to harm your machine. Therefore, it’s a good idea to scan your system to see if there are any problems.

That’s why, in most cases, when a new.dll file appears on your computer, it’s accompanied by an an.exe file. Make sure you can both simultaneously, so you don’t have to bother about your computer getting infected.


How to remove this file?

If none of the above troubleshooting procedures have worked, you can take a more active approach and download and replace the proper SteamUI.dll file version.

  1. Find your Windows os version in the “Download SteamUI.dll Files” section.
  2. Download your Windows file type by clicking the corresponding “Download Now” button.
  3. Place this file in the Steam folder where it belongs.
  4. You should restart your computer. If this final phase fails and the issue persists, your only option left is to perform a clean installation of Windows 10.
