Installing Multiple versions of Internet Explorer with Multiple_IE

I don’t have the time, inclination or grunty machines to play around with Virtual machines just so I can test a website in IE6 (after IE7 ‘magically’ appeared).  When I say ‘test’, I actually mean hack an IE-specific CSS together with some box-model workarounds.  I digress…


Enter Multiple_IE.  It’s not perfect (it’s a hack in itself), but it suffices in most cases so kudos for that…  You even get the nostalgia of IE3

Enable any user to increment Performance Counters

I thought I was being a bit clever some time back when I wrote a little .NET wrapper for performance counters, largely for the reason of allowing clients to happily work with counters that weren’t installed on their machine.  The default behaviour is an exception when you attempt to use a non-existant counter.


This was all good until deployment to servers and clients with ‘real’ non-admin users.  I then read that only administrators and power users could increment counters (awww!).


I just found this MS article that explains how to get around this as the ‘permissions’ are simply based on registry permissions for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib.


To set the permissions,



  1. Open Regedit to that key
  2. Right-click, select ‘Permissions…’
  3. Add your user’s groups or specific name with ‘Full Control’

I can now actually implement the solution (1 year on!)
