Issue: How to fix Steam fatal error “Failed to load Steamui.dll”?
Hello. Since yesterday, I can't open Steam because of “Fatal error, failed to load steamui.dll.” Is there anything that could be done about this? I can't play my games because of this. Help would be appreciated.
Solved Answer
Steam gaming platform has been around for almost two decades by now, and almost all users who play video games have it installed on their systems. This is rather unsurprising, considering that the platform hosts over 50,000 games[1] to choose from and the continuous discounts that players can get.
The Steam client, while well optimized and easy to understand, still suffers from its fair share of technical difficulties. This time, we are talking about the “Failed to load Steamui.dll” error, which users receive either when launching the app or when trying to install it on their systems for the very first time.
Steamui.dll is a Dynamic Link Library file, which is similar to an executable file and is used to execute code and elements that are required in the particular time frame. Unlike EXE[2] files, these can't be executed directly and need a host for that. There are plenty of DLL files within the Windows operating system, although there are thousands of imported ones as well.
In this case, the file is related to the Steam UI file, which ensures that the app runs smoothly and servers are executed correctly. If this element fails to load for one reason or another, the result is Failed to load Steamui.dll” error. Consequently, users can no longer launch the platform, as well as can't play games installed on it.
There are many reasons which could cause the issue. For example, corrupted system files or Steam client. Below we provide several methods that should help you fix the “Failed to load Steamui.dll” error, although before you proceed, we recommend you run a scan with a PC repair software RestoroMac Washing Machine X9. It can find and replace corrupted system files automatically; the app can also be useful in the future when dealing with BSODs,[3] crashes, or similar problems.
Fix 1. Run the app as an administrator
Let's start with simple solutions. In some cases, the app might not run correctly without sufficient rights. Thus, you should right-click the Steam EXE file (or the shortcut) and select Run as administrator. If that helped, use the following instructions to make the app run as administrator automatically every time you launch it:
- Right-click on the Steam icon and select Properties
- Go to the Compatibility tab
- Mark the Run this program as an administrator option
- Click Apply and OK.
Fix 2. Try deleting Libswscale-X.dll and SteamUI.dll files
Steam file corruption might be causing the launcher to crash. You can delete the files, and Steam should re-download the missing ones once you launch it:
- Right-click on Steam shortcut and select Properties
- At the bottom of the window, click Open File Location
- Find the Libswscale-X.dll file (the “X” represents version number, it could be 3,4 or 5) and delete it with keyboard combination Shift + Del
- Do the same thing with SteamUI.dll
- Try launching the client.
Fix 3. Add parameters into Steam's shortcut
There is a way to fix this by deleting Steam files in Safe Mode, although at this point, it would be better to proceed with the step below. Instead, you could add the following parameters into Steam's shortcut:
- Right-click on Steam shortcut or EXE file and select Properties
- In the Shortcut tab, under Target, type in the following commands after the file's location:
-clientbeta client_candidate - For example, it should look as follows:
“C:\\Program Files (x86)\\Steam\\Steam.exe -clientbeta client_candidate” - Click Apply and OK.
Fix 4. Delete package and bin folders
Another thing you could try is deleting bin and package folders from Steam's directory.
- Right-click on the Steam shortcut or EXE file and select Properties
- At the bottom of the window, click Open File Location
- Locate package folder, press Shift + Del on your keyboard
- Do the same with the bin folder
- Double-click Steam.exe – it will re-download the missing files.
Fix 5. Reinstall Steam
If none of the solutions above helped, you should reinstall the app altogether. You won't lose your games. Just be aware you'll have to log in using the correct credentials.
- To keep your games, move the steamapps folder out of the C:\\Program Files (x86)\\Steam directory
- Type Control Panel in Windows search and hit Enter
- Go to Programs > Uninstall a program
- From the list, find Steam
- Right-click and select Uninstall
- Wait till the process is finished
- Re-download the app from its official website.
