How to fix error 0x8007045A in Windows?

To solve this problem, you have three options:

  1. Run a system file check. In some cases, this can help resolve the issue.
  2. Replace work files on your system by files msxml3.dll , Msxml3a.dll , Msxml3r.dll , msxml6.dll and msxml6r.dll . If you have another computer, copy these 5 files from another system to the C: \ Windows \ System32 folder of the problematic system and replace the damaged files. Make sure both computers are running the same version of Windows.

After that you will need to re-register the DLL files:

To save a dll or ocx file, open a Windows command prompt with administrator rights, type the following command and press Enter:

regsvr32 “path and filename of dll or ocx“

regsvr32 C: \ Windows \ System32 \ msxml3.dll

Do the same for the other four files – msxml3a.dll, msxml3r.dll, msxml6.dll, and msxml6r.dll.

Restart your computer .

  1. If that doesn’t work for you, you have another option. Download the latest XML parser from MSDN and install it on your computer.
