The probability that you’re Windows user and you never saw any DLL error is in the domain of science fiction. They frequent missing DLL files are mostly related to DirectX or redistributables, but even the minor DLL file like bcrypt.dll can occur from time to time. This file is essential for running certain applications and if it’s not in its place when called, the error “bcrypt.dll missing…” will occur.

For the purpose of addressing this, we prepared a list of viable solutions. If you’re stuck with the error at hand, make sure to follow them closely and we should be in the clear.

How to fix “bcrypt.dll missing…” error in Windows 10

  1. Run SFC
  2. Clean junk files
  3. Scan for malware
  4. Reinstall the affected program
  5. Reset PC to factory settings

1: Run SFC

Before we move on to solutions, we recommend updating your system. It seems that in a lot of instances major updates disrupt the system. Not a single major update came without some issues and this can be one of them. Especially if you’re upgrading from Windows 7 to Windows 10. It seems, looking at the reports, that this error mostly strikes users who’ve done just that. So, navigate to Settings > Update & Security > Windows Update, and check for available updates. That might fix the problem.

Another thing worth mentioning concerns the malicious sites which offer DLL files for free. Don’t download missing DLL files and add them manually to System folder. At least if you don’t want malware on your system or to disrupt the system completely. With that said, let’s move to the first solution.

System File Checker is a utility tool run the elevated Command Prompt. Its main purpose is to locate the system files with the false integrity or corruption and replace them accordingly. Follow these steps to run it and fix the error on Windows 10:

  1. Press Windows + S to open Windows Search bar.
  2. Type cmd.bcrypt.dll windows 10
  3. Right-click on Command Prompt and run it as an administrator.
  4. In the command line, type sfc/scannow and press Enter.bcrypt.dll windows 10
  5. After the procedure ends, restart your PC.

If the issue still persists, we recommend trying a 3rd party solution.

Run a third-party DLL fixer

There are plenty of third-party programs out there that promise to fix or replace missing or broken DLLs, and most of them stay true to their word. However, if you are to choose just one, then there’s no way you can go wrong with Restoro.

How to use Restoro to fix missing or broken DLLs

  1. Download here Restoro and install it on your Windows 10 PC
  2. Let Restoro perform a full system scan
  3. When the scan is finished, press Clean Now
    • This is when you will have to activate your license key
    • Before the repair process starts, Restoro will create a restore point of your system in case things go wrong
  4. Restoro will now proceed to fix your DLL-related issue.

Note: While Restoro can be downloaded for free, it has limited functionality until you activate it. That being the case, if you want the full benefit of a great PC repair and optimization tool, you should purchase the full license.

2: Clean junk files

In general, Windows stores a lot of redundant files. They often take a lot more space than usual on your system partition and can, in the worst case scenario, cause certain issues. Which can be likely in with the “bcrypt.dll missing…” error. For example, after upgrading from Windows 7 to Windows 10, a lot of Windows 7 files will pass to Windows 10. In this case, the bcrypt.dll from Windows 7 might collide with the one on Windows 10. This might be a long stretch, but system DLL files tend to mix up occasionally.

In order to resolve this, we recommend deleting all cluttering junk files from your system. Some users might turn to a third-party solution for this action, but we prefer Disk Cleanup. This is a native utility and the risk of deletion of important files is close to zero.

Here’s how to run the Disk Cleanup tool and delete all junk files from your Windows 10:

  1. Press Windows key + S to open Search bar.
  2. Type in dsk and open Disk Cleanup.bcrypt.dll windows 10
  3. Choose the system partition and click OK.bcrypt.dll windows 10
  4. Click on Clean system files and choose the system partition again. The calculation can take some time.
  5. Check all boxes and click OK.

3: Scan for malware

As we all know, the mother lode of your system is in the System32 folder. That’s where the bcrypt.dll is to be found and that’s where the malware will likely attack. Most of the time, with the proper protective software, you don’t have to worry about the thing. However, it’s still well advised to scan your system for possible infections from time to time.

In this scenario, there’s a chance that the malware affected the bcrypt.dll file or is mimicking it. For that reason, make sure to perform the deep scan (the most in-depth scan your tool offers) and confirm that’s not the case. For obvious reasons, we’ll explain how to do it with Windows Defender which every Windows 10 user has at its disposal. The instructions are below:

  1. Open Windows Defender from the taskbar notification area.
  2. Choose Virus & threat protection.bcrypt.dll windows 10
  3. Open Run a new advanced scan.bcrypt.dll windows 10
  4. Select Windows Defender Offline Scan and click Scan now.bcrypt.dll windows 10
  5. Your computer will restart and the scanning procedure will start.

In case Windows Defender does not find anything harmful but the problem still persists, we strongly recommend you to download Bitdefender, world’s Nr. 1 antivirus and to scan your PC with it. It will surely clean all junk/malware-infected files and restore your system’s functionality.

4: Reinstall the affected program

This DLL file, like so many others, is an integral part of communication between the system and third-party applications or games. The error at hand will most likely pop-up while you’re trying to start the game or application. In order to address this (after you took the previous steps), we recommend reinstallation of the affected program which won’t start.

You should have an easy time reinstalling any given application, but just as a reminder, here are the steps you’ll need to follow:

  1. In the Windows Search bar, type Control and open Control Panel from the list of results.bcrypt.dll windows 10
  2. From the Category view, click Uninstall a program under Programs.bcrypt.dll windows 10
  3. Uninstall the game/application which invokes the error.
  4. Download the latest installation package and install it again.

5: Reset PC to factory settings

Finally, even though bcrypt.dll is minor Dynamic Link Library file, the reoccurring error might get over your head. If that’s the case, we recommend resetting your PC to factory settings. It sounds distressing but it really isn’t. I’ve factory reset PC more than a dozen times over the period of few years and never lost a chunk of data. This is a frequently overlooked advantage of Windows 10.

After you reset your PC to factory settings, everything should be fine and the error will perish. Follow these instructions to perform a factory reset on Windows 10:

  1. Press Windows key + I to summon the Settings app.
  2. Open the Update & Security section.bcrypt.dll windows 10
  3. Choose Recovery.
  4. Under ”Reset this PC”, click Get started.bcrypt.dll windows 10
  5. Preserve your files when prompted and continue with the procedure.

That’s a wrap. Hopefully, this was a helpful read and the error at hand is gone. Don’t forget to tell us about the results or provide the alternative solutions in the comments section below.
