CAUSE
This behavior occurs because the PATH environment variable does not include the %SystemRoot%\System32\WBEM folder.
RESOLUTION
To resolve this behavior, add the %SystemRoot%\System32\WBEM folder to your PATH environment variable. To do so, follow these steps:
1. Right-click My Computer, and then click Properties.
2. On the Advanced tab, click Environment Variables.
3. Under System Variables double-click the PATH environment variable.
4. Type:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\system32\WBEM
Note If other system variables appear, do not remove them.
5. Click OK, and then click OK.
