Hello,
In Windows Vista, even though you are an administrator, programs that do not
ask to use your admin power ("Windows needs your permission to continue")
are not allowed to use it.
Programs designed for Vista will ask you for this permission whenever they
require it.
Older programs will not know how to do this, so you must manually give them
such permission. Right-click on them and click Run As Administrator.
