[python-win32] Win32pdhutil - GetFormattedCounterValue while running python thu IIS

[sebastien Pastor]

Thomas a real big thanx for pointing me into the right direction:

I used your code that gave a me an access denied message while trying to 
access the  "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows 
NT\CurrentVersion\Perflib" key (apparently used to find out which 
language to expect)
So i ll gave read permission on this key to IUSR user and now it is 
working like a charm.

U really  saved my day ! Merci ! :-)

Cheers

Seb
