Before your try out our tested solutions, you should:

1. Run the DISM and SFC commands

  1. Hold Windows + S to open the Start menu. Search for Command Prompt and choose Run as administrator.cmd-0x8007045a

  4. Restart your PC.

The System File Checker scan is a native Windows component that searches and restores damaged system files. An empty window, as a result, means no corrupted ones have been found.

2. Replace the damaged files and re-register them

  1. Copy these DLL files from a device that is working fine to yours: msxml3.dll, msxml3a.dll, and msxml3r.dll. They should be in the following directory: C:\Windows\System32dll-files-0x8007045a
  2. Register the files by pressing Windows + R to open the Run dialog.0x8007045a-run
  3. Start with the first by typing the following in the open box and clicking OK: REGSVR32 C:\WINDOWS\SYSTEM\MSXML.DLL0x8007045a-register-dll
  4. Re-register the second file by repeating the first two steps, but this time typing the command below, followed by clicking Enter: REGSVR32 C:\WINDOWS\SYSTEM\MSXML2.DLL
  5. Repeat the process for the last file by typing this command and clicking Enter: REGSVR32 C:\WINDOWS\SYSTEM\MSXML3.DLL
  6. Restart your PC.

Malicious software can infect your DLL files and cause various errors, including this one. To ensure your system is protected against such threats, perform regular checks using Virus & threat protection or a trusted anti-malware program.

If you panic and force a reboot, this could mean you can lose important data in the process. Don’t forget to always back up your important files!

Congrats! This should help you get rid of the frustrating 0x8007045a ERROR_DLL_INIT_FAILED error.
