Solution
Probably your windows registered name have a special character like "*". I suggested to you change windows registered name. you can change it from registry in (Win XP):
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
change value of these keys: RegisteredOrganization RegisteredOwner
