Hi All,

Good Day!

I am in the process of implementing intelperformancecountermonitorv2.3a (Intel PCM) in one of our windows 7 machine which is configured as

  1. Windows 7 Enterprise (SP 1)
  2. Intel(R) Core(TM) Duo CPU E7500 @ 2.93GHz 2.93GHz
  3. 32bit operating system

As given in Windows_Howto document built pcm.exe utility (used Win Ring open source downloaded from Real Temp 370, copied all 4 dll and sys files as suggested)

When I tried to run the pcm.exe from cmd (with admin rights), I got the below given error

pcm.exe 1 -nc -ns

Intel(r) Performance Counter Monitor V2.3 (2012-09-20 10:00:15 +0200 ID=ccfb40f)
