Was also getting errors when it was installed but not profiling which led me to uninstall it. –Rush Frisby Sep 4 '14 at 6:19 add a comment| 6 Answers 6 active oldest votes up vote 15 down vote accepted After much searching I found that someone had previously installed dotTrace, then uninstalled it, however the uninstall wasn't very clean and had left the registry littered with entries, though we'd removed some entries we thought could stop the problem there were more specific to that profiler. After removing all registry entries related to dottrace and the CSID it presented we no longer have the error appearing in the event viewer. share|improve this answer answered Apr 5 '12 at 8:12 Dale 8661924 3 Also had this probl

When examining the application event log, the following entry is shown: Event Type: ErrorEvent Source: .NET RuntimeEvent Category: NoneEvent ID: 1022Date: 14/10/2008Time: 14:38:17User: N/AComputer: MINEDescription:.NET Runtime version 2.0.50727.1433 - Failed to CoCreate profiler. For more information, see Help and failed to cocreate Support Center at http://go.microsoft.com/fwlink/events.asp. One possible cause for this error is that the ASPNET user does not have read permissions to the ANTS Profiler program directory. The ASP .NET worker process needs to load ProfilerCore.dll (RedGate.Memory.Core.dll for memory profiler) in order to send profiling metrics from the worker process to ANTS Profiler.By default, ASP .NET web applications run under the local machine's ASPNET user account in IIS version 5. This is configurable, however, in the processModel section of the machine.config file. For example, if the ASP .NET web application uses the .NET 2.0 runtime, the location for the configuration file will be "%systemroot%\microsoft.net\framework\v2.0.50727\config\machine.config" If the processModel is set to "Autoconfig=Yes", then ASP .NET is also using the ASPNET account.In IIS version 6 and 7, the web application pool's Windows user is configurable. It's normally the user that runs the application pool (for instance NT AUTHORITY\NETWORK SERVICE).Once you have determined the correct account that runs ASP .NET code, you may use Windows Explorer to grant READ permissions to the Profiler installation folder (%programfiles%\red gate\ants profiler
