Fix: NET Parsing Error 0xC00CE556

Among the many errors and issues that plague the Windows Operating System is parsing error 0xC00CE556. Parsing error 0xC00CE556 may present itself when you try to install a program or open a program or even when you simply boot your computer up and open the Desktop. Parsing error 0xC00CE556 is not only intrusive but can also inhibit you from carrying out various functions on your computer, which is why it needs to be dealt with. The following are the two solutions that you can use to get rid of parsing error 0xC00CE556: Parsing error 0xC00CE556, to elaborate, is an error message that states something along the lines of:

Error parsing C:\\Windows\Microsoft.Net\Framework\v2.0.50727\Config\machine.config Parser returned error 0xC00CE556

Solution 1: Replace the corrupt machine.config file with the default one

In almost all cases, Windows starts spewing out parsing error 0xC00CE556 when it tries to parse the machine.config file in the directory “C:\\Windows\Microsoft.Net\Framework\v2.0.50727\Config\” but fails because machine.config is corrupt. Since that is the case, simply replacing the corrupt machine.config file with a fresh, default one should get rid of the problem.

Hold the Windows Key and Press R. In the run dialog; type





Look for a file named machine.config.default. Move/Copy machine.config.default to a new location – the Desktop, for example.


Back in the C:\\Windows\Microsoft.Net\Framework\v2.0.50727\Config\ directory, delete the corrupt machine.config file.

Go back to the machine.config.default file, and rename it to machine.config. If asked by your computer whether or not you really want to mess with the file extension, confirm the action.

Move the new machine.config file to C:\\Windows\Microsoft.Net\Framework\v2.0.50727\Config\.

Close File Explorer and restart your computer.

Once your computer boots up, you should no longer receive parsing error 0xC00CE556.

Solution 2: Perform a clean reinstall of your Operating System

In the event that you are experiencing from parsing error 0xC00CE556 and Solution 1 does not work, which is highly unlikely, the only option you have left is to perform a clean reinstall of your Operating System.

Regardless of what problem the Microsoft .NET Framework on your computer is plagued with, reinstalling Windows will definitely solve it and get your computer working as it should be.


  1. I am able to solve this problem occurring after up gradation from Win7 Pro to Winn10Pro, which failed giving an unknown reason. As a result the Lenovo solution centre stopped responding. I followed exactly the procedure as outlined in this article, but changing from Framework to Framework64 in the RUN dialog box as the error in my laptop is referring to that. Thanks Kevin, God bless uou

  2. Thank you, that fixed it. But omg your explanation is so long for just the simple command “cp -fo C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGmachine.config.default C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGmachine.config” in an administrative Powershell…
