Error "The type initializer for 'Microsoft.Exchange.Diagnostics.ExTraceConfiguration' threw an exception."

After installing KB2506143 "Windows Management Framework 3.0" having problems using Powershell scripts for Microsoft Exchange 2010 with the following error "The type initializer for 'Microsoft.Exchange.Diagnostics.ExTraceConfiguration' threw an exception.". Windows offers a search solution on the Internet, but found nothing. Therefore, we must do the following:
1. Reinstall Exchange Manage Tools
2. In batch scripts to add the parameter "%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -version 2.0"
3. Rename or delete folders in profile "%userprofile%\AppData\Roaming\Microsoft\Exchange\RemotePowerShell"
