Running the following code result in an error if the key "Users" doesn't exist in the registry.

goWsHost = CreateObject("WScript.Shell") && initiate Windows Scripting Host

REGKEY_LOC = "HKEY_CURRENT_USER\Software\Ifö Ceramics AB\PiDoc\1.0\Window Positions\Users"

* Next line gives an error saying it can not open the registry key.
lcBuffer = goWsHost.RegRead(REGKEY_LOC)

Well i understand that it can not, but how can i query the registry to check for the existance of the key or att least avoid the error message ?
