Our software package works fine under XP but when I run under Vista RC1
as an administrator I get the following exception:

Exception has been thrown by the target of an invocation. --->

At this spot in the code we are trying to create a performance counter
group with performance counters inside it. I can not seem to find any
information anywhere on what has changed in Vista to cause this. I am
running as an administrator on the machine and am in the Performce
Counter groups in Vista. Any thoughts or pointers would be appreciated.
