fix bcrypt hash could not be located error

We recently came across the McUICnt.exe Entry Point not found, The procedure entry point BCryptHash could not be located in the dynamic link library bcrypt.dll error on several devices, some running Windows 7.

On closer inspection, the problem appeared to be with bycrypt.dll, a system file. BCryptHash is an encryption algorithm used to store critical data securely. As per Microsoft’s official page, BCryptHash works only on Windows 10 or later iterations of the OS.

So, to start with, make sure your PC meets the minimum system requirements for BCryptHash.

How do I fix the BCryptHash could not be located error?

1. Use a DLL repair tool

Your primary approach when any error message lists a DLL should be to use an effective DLL repair tool, as it can identify replacements automatically.

2. Copy the DLL from another PC

If you have another PC running the same Windows iteration and architecture (32-bit or 64-bit), moving a copy of bcrypt.dll would also work. The file is stored in: C:\Windows\System32

System32 folder

On the other PC, locate the bcrypt.dll file and move it to an external drive. Now, rename the existing bcrypt.dll on the affected PC as bcrypt.old.dll, and finally, transfer the DLL from the external drive to the System32 folder.

Remember not to delete the existing DLL (that we renamed) unless the new one works fine, and you don’t receive the BCryptHash could not be located anymore.

3. Run the DISM and SFC scans

  4. Now, run the SFC scan with this command: sfc /scannowsfc scan to fix bcrypt hash could not be located
  5. Once done, reboot the PC and check for improvements.

Given that corrupt system files, bcrypt.dll being one, can trigger DLL errors, running the SFC scan and DISM commands got things running for us in 3 out of 5 cases.

This also helps when vcomp100.dll is not found.
