“加载 steamui.dll 失败”错误自Steam出现以来一直困扰着它，不幸的是，今天仍然存在。而且这也不总是Steam的错——从损坏的文件到丢失的Windows 更新(Windows Updates)，有一系列外部因素可能是造成的。
好消息是它通常很容易修复，不像Steam 无法启动(Steam fails to launch)而没有任何错误消息。因此，这里有最好的方法来消除这个恼人的错误并重新开始玩你最喜欢的视频游戏。
修复 1：重新安装 Steam
大多数情况下，“无法加载 steamui.dll 错误”是由丢失或损坏的文件引起的。解决该问题的最简单方法是卸载并重新安装Steam。
您不必担心丢失您正在玩的任何游戏的进度，因为卸载Steam时保存文件不会被删除。但是，游戏本身已被删除，因此只有在您愿意重新安装它们时才这样做。
- 首先卸载Steam。从控制面板(Control Panel)打开添加(Open Add)或删除程序，或者从开始菜单(Start Menu)中搜索它。
- 在应用列表中搜索 Steam 以找到客户端。
- 调(Bring)出三点并选择Uninstall。
- 您将被要求再次确认您的选择。
- Steam 卸载程序(Steam Uninstaller)现在将打开。再次选择卸载 -(Select Uninstall –)最终从您的计算机中删除 Steam。
现在我们将再次安装 Steam。
- (Download)从Steam 主页(Steam homepage)下载最新版本的安装程序。
- 运行安装程序以在您的计算机上安装Steam 。
- 安装完成后，打开Steam。让它下载它检测到的任何更新。
- 登录您的Steam帐户，您就可以开始使用了。如果一切顺利，您应该能够毫无问题地查看Steam商店和您的库。(Steam)
修复 2：清除下载缓存
如果您在最近下载的游戏中遇到此错误，则下载缓存(Download Cache)可能有问题。简单地(Simply)清除缓存通常可以让Steam正确启动视频游戏。
- 要清除下载缓存(Download Cache)，首先启动Steam客户端。
- 在 Steam 菜单中，选择设置。
- 切换到下载(Downloads)选项卡，然后点击清除下载缓存(CLEAR DOWNLOAD CACHE)按钮。
- 您将看到一个对话框，警告您有关此操作的结果。选择确定(Select OK)继续。
再次登录(Log)Steam，看看您现在是否可以畅玩问题游戏而不会出现任何错误。
修复 3：删除 libswscale-x.dll 和SteamUI.dll 文件(SteamUI.dll Files)
损坏的SteamUI.dll文件是导致“加载 steamui.dll 失败”错误的最常见原因。重新安装 Steam 是最明显的解决方案，尽管有些人可能不愿意重新安装他们的整个游戏库。
另一种方法是删除SteamUI.dll和Libswscale-x.dll文件。Steam客户端将在您下次启动时自动下载丢失的文件。
- 要删除有问题的文件，您必须首先导航到Steam的安装目录。最简单的方法是从其桌面快捷方式中找到路径。首先右键单击Steam快捷方式并选择属性。
- 在Shortcut选项卡（它应该打开的位置）中，您会找到一个按钮，显示Open File Location。点击(Click)它。
- 您现在将被直接带到包含Steam的目录。查找(Find)并删除SteamUI.dll和 libswscale-x.dll 文件。请注意，x 将替换为整数，例如 libswscale-3.dll 和 libswscale-5.dll。
- 现在只需重新启动Steam，客户端就会自行更新以修复丢失的数据。
如果问题是由损坏的DLL文件版本引起的，这将解决问题。
修复 4：删除Steam的Beta 版(Beta Version)
与大多数不断更新的应用程序一样，Steam拥有一个具有最新功能（和大量错误）的尖端测试版。
由于您必须手动选择Steam 客户端测试版(Steam Client Beta)，因此在大多数情况下您不必担心这一点。但如果您使用的是Steam客户端的测试版，最好将其删除并再次尝试运行Steam。
您无需卸载Steam即可移除Beta。只需(Just)删除 Beta 包文件，Steam将负责其余的工作。
- 首先，导航到Steam文件夹。您可以在上一个修复程序中找到定位步骤。
- 打开包文件夹。如果您在Steam Beta上，您会在顶部找到一个名为该文件的文件。删除它。
- 重新启动(Reboot)计算机并运行Steam。它将更新客户端并再次正常运行。
如果它源于测试版中的故障，这将修复“加载 steamui.dll 失败”错误。
修复 5：扫描恶意软件
虽然不常见，但病毒可能会感染您的Steam目录，破坏DLL文件并阻止Steam正常启动。在这种情况下，您最好的办法是扫描您的计算机以查找恶意软件(scan your computer for malware)。
您可以为此使用任何防病毒应用程序，尽管Windows Defender是默认情况下出现在每台Windows计算机上的绝佳选择。
- 要使用Windows Defender(Windows Defender)扫描您的 PC ，请打开 Windows 安全中心的病毒和威胁防护选项卡。您可以通过从“开始”菜单(Start Menu)中搜索来找到它。
- 您可以执行快速扫描(Scan)，但我们建议选择按钮正下方的扫描选项。(Scan)
- 选择全面扫描(Select Full Scan)并点击立即扫描(Scan)按钮。
完整扫描需要一段时间，因此您可能需要等待一段时间。但是一旦扫描完成，您的 PC 应该没有恶意软件。重新启动计算机并再次运行Steam。
修复 6：检查硬盘驱动器是否有错误
如果上述修复均不适合您，则您可能正在处理出现故障的硬盘驱动器。未检测到的坏扇区通常会引发奇怪的错误，因为操作系统无法访问写入它们的数据。
解决此问题的最佳方法是使用系统文件检查器(System File Checker)( SFC ) 扫描驱动器。SFC 是一个 CMD 实用程序(SFC is a CMD utility)，它遍历受保护的系统文件，修复发现的任何损坏的文件。
- 要使用SFC(SFC)扫描硬盘，您需要打开命令提示符(Command Prompt)。您可以通过在开始(Start)菜单中搜索CMD来找到它。(CMD)
- 输入(Enter)sfc /scannow 以扫描驱动器以查找逻辑错误。
- SFC现在将开始扫描磁盘，修复发现的任何损坏的系统文件。不需要太长时间，但让过程完成。完成后重新启动 PC。
由于SFC修复了任何损坏的Windows文件，因此现在将修复由于操作系统引起的任何错误。
修复“加载(Load)steamui.dll失败”错误(” Error)的最佳方法是什么？
每当遇到Steam(Steam)错误时，重新安装应用程序的通用补救措施应该是您的第一步。如果这不是一个选项，您可以随时尝试删除SteamUI.dll并允许Steam替换该文件。
除了损坏的DLL文件外，问题还可能源于Steam中的技术故障。清除下载缓存(Download Cache)并删除 Beta 包可以解决此类问题并使其再次运行。
如果这些方法都不起作用，则问题可能出在您的 PC 本身上。使用 Windows Defender 对系统进行病毒扫描(Use Windows Defender to scan the system for viruses)，并使用命令行工具检查硬盘是否有数据损坏。如果发现任何问题，请重新启动计算机并重新安装Steam。您应该可以再次正常玩游戏(play your games normally)了。
6 Best Ways to Fix the “Failed to Load steamui.dll” Error
The “Failed to load ѕteamui.dll” error has plagued Steam since its advеnt and іs, unfortunately, still present tоday. And it isn’t always Steam’s fault either – from corrupted files to missing Windows Updates, there is a range of external faсtors that could be responsible.
The good news is that it’s usually rather easy to fix, unlike when Steam fails to launch without any error message. So here are the best ways to remove this irritating error and get back to playing your favorite video games again.
Fix 1: Reinstall Steam
Most of the time, the “Failed to load steamui.dll error” is caused by missing or corrupted files. And the easiest way to fix that problem is to uninstall and reinstall Steam.
You don’t have to worry about losing your progress in any of the games you were playing, since save files are not deleted upon uninstalling Steam. The games themselves are removed, though, so only do this if you’re willing to reinstall them again.
- Begin by uninstalling Steam. Open Add or remove programs from the Control Panel, or just search for it from the Start Menu.
- Search for Steam in the app list to find the client.
- Bring up the three-dot and select Uninstall.
- You will be asked to confirm your choice again.
- The Steam Uninstaller will now open. Select Uninstall – again – to finally remove Steam from your computer.
Now we will install Steam again.
- Download the latest version of the installer from the Steam homepage.
- Run the setup to install Steam on your computer.
- Once the installation is complete, open Steam. Let it download any updates it detects.
- Sign in to your Steam account, and you’re ready to go. If everything went well, you should be able to view the Steam store and your library without any issues.
Fix 2: Clear the Download Cache
If you are getting this error in a game you recently downloaded, the Download Cache might be at fault. Simply clearing the cache often enables Steam to launch the video game properly.
- To clear the Download Cache, first launch the Steam client.
- In the Steam menu, select Settings.
- Switch to the Downloads tab, and hit the CLEAR DOWNLOAD CACHE button.
- You’ll get a dialog box warning you about the results of this action. Select OK to continue.
Log in to Steam again and see if you can play the problem game now without any errors.
Fix 3: Delete the libswscale-x.dll and SteamUI.dll Files
A corrupted SteamUI.dll file is the most common reason for getting the “Failed to load steamui.dll” error. Reinstalling Steam is the most obvious solution, though some people may balk at having to reinstall their whole library of games again.
An alternative is to just delete the SteamUI.dll and Libswscale-x.dll files. The Steam client will then automatically download the missing files the next time you launch it.
- To delete the offending files, you must first navigate to Steam’s installation directory. The easiest way to do this is by finding the path from its desktop shortcut. Begin by right-clicking on the Steam shortcut and selecting Properties.
- In the Shortcut tab (which is where it should open) you will find a button saying Open File Location. Click on it.
- You will now be taken straight to the directory containing Steam. Find and delete the SteamUI.dll and libswscale-x.dll files. Note that the x will be replaced by an integer, like libswscale-3.dll and libswscale-5.dll.
- Now just relaunch Steam and the client will update itself to repair the lost data.
This will fix the issue if it was being caused by corrupted versions of the DLL files.
Fix 4: Delete the Beta Version of Steam
Like most constantly updating applications, Steam has a cutting-edge beta version with the latest features (and plenty of bugs).
Since you have to manually opt for Steam Client Beta, you don’t have to worry about this in most cases. But if you are using a beta version of the Steam client, it’s a good idea to remove it and try running Steam again.
You don’t have to uninstall Steam to remove Beta. Just delete the beta package file and Steam will take care of the rest.
- First, navigate to the Steam folder. You can find the steps to locating in the previous fix.
- Open the package folder. If you’re on Steam Beta, you will find a file named that right at the top. Delete it.
- Reboot your computer and run Steam. It will update the client and run as normal again.
This will fix the “Failed to load steamui.dll” error if it originated from a glitch in the beta version.
Fix 5: Scan for Malware
Though uncommon, it is possible for viruses to have infected your Steam directory, corrupting the DLL files and preventing Steam from launching properly. In such a scenario your best recourse is to scan your computer for malware.
You can use any antivirus application for this, though Windows Defender is a great choice present by default on every Windows computer.
- To scan your PC with Windows Defender, open Windows Security’s Virus & threat protection tab. You can find it by searching from the Start Menu.
- You can perform a Quick Scan, though we recommend selecting Scan options right below the button instead.
- Select Full Scan and hit the Scan now button.
A full scan takes a while, so you may have to wait for a while. But once the scan is done, your PC should be free of malware. Restart your computer and run Steam again.
Fix 6: Check Hard Drive for Errors
If none of the fixes above have worked for you, it is possible that you are dealing with a malfunctioning hard drive. Undetected bad sectors can often throw weird errors, as the operating system is unable to access the data written on them.
The best approach for solving this is to scan the drive with the System File Checker (SFC). SFC is a CMD utility that goes through protected system files, repairing any corrupted files discovered.
- To scan your hard disk with SFC, you need to open the Command Prompt. You can locate it by searching for CMD in the Start menu.
- Enter sfc /scannow to scan your drive for logical errors.
- SFC will now begin scanning the disk, repairing any broken system files found. It doesn’t take too long, but let the process complete. Restart your PC when you are done.
Since SFC repairs any corrupted Windows files, any errors due to the operating system will now be fixed.
What Is the Best Way to Fix the “Failed to Load steamui.dll” Error?
The universal remedy of reinstalling the application should be your first step whenever facing a Steam error. In case that is not an option, you can always try deleting the SteamUI.dll and allowing Steam to replace the file.
Apart from a corrupted DLL file, the problem can stem from technical glitches in Steam. Clearing the Download Cache and removing the beta package can fix such issues and get it working again.
When none of these methods work, the issue might lie with your PC itself. Use Windows Defender to scan the system for viruses, and use command-line tools to check the hard disk for data corruption. If any problems are found, restart the computer and reinstall Steam again. You should be able to play your games normally again.
