Unable to run dHeapMon - Desktop Heap Monitor

Hi

I need to check for memory leakage for a developer who suspects this is the issue and need to rule this out.

I found the dHeapMon - Desktop Heap Monitor on the internet.

I can install it but not run it due to an error 50.

I'm running this on Windows 2008 R1 SP2 32 bit server.

C:\kktools\dheapmon8.1\x86>dheapinst -y srv*.*http://msdl.microsoft.com/download/symbols
  dheapinst - Desktop Heap Monitor installed successfully


C:\kktools\dheapmon8.1\x86>dheapmon -l

Desktop Heap Information Monitor Tool (Version 8.1.2925.0)
Copyright (c) Microsoft Corporation.  All rights reserved.
  DheapmonLoadDriver() was failed. Error (50)

Please can anyone help.

Kind Regards

Matthew

p.s I load these commands in the Command Window as Administrator and changed the compatibility of the files to Windows 2003 (Service Pack 1) but still get the error 50.
