Windows 8 CP: error parsing c:\windows\microsoft.NET\framework\v2.0.50727\config\machine.config parser returned error 0xC00CE556

In Windows 8 DP, .NET 2.0 application running, the following error message:
error parsing c:\windows\microsoft.NEt\framework\v2.0.50727\config\machine.config parser returned error 0xC00CE556

Solution:
Go in the “c:\windows\microsoft.NET\framework\v2.0.50727\config” directory, and renamed the “machine.config” to “machine.config.backup”, and then copied the “machine.config.default” to “machine.config”, worked fine.
