CoCreateInstance errors: No profiler log

To verify whether the permissions error is due to profiler errors:

1. Check your application event log for errors like this:

   NET Runtime version 4.0.30319.296 - Loading profiler failed during CoCreateInstance. Profiler CLSID: '{FF68FEB9-E58A-4B75-A2B8-90CE7D915A26}'

   コピー

2. Compare the CLSID in the error to New Relic's CLSIDs:

   71DA0A04-7777-4EC6-9643-7D28B46A8A41
   FF68FEB9-E58A-4B75-A2B8-90CE7D915A26

   コピー

3. Do one of the following:

   • If the CLSID does not match, uninstall the other profiler.
   • If the CLSID does match, continue with this procedure to check the profiler logs for CoCreateInstance permissions errors.

To verify that the New Relic assemblies are attached to the w3wp.exe process:

1. On the server where your app is installed, download the Microsoft Windows Sysinternals Process Explorer.

2. Unzip the file and run procexp.exe as an Administrator.

3. Select View > Show Lower Pane, then select View > Lower Pane View > DLLs.

4. Generate some traffic to your app.

5. To update the process list, select View > Refresh Now.

6. In the top pane, select your service or w3wp instance (typically nested under a svchost.exe process).

7. In the bottom pane, look for assemblies whose names begin with NewRelic, including:

   NewRelic.Agent.Core.dll
   NewRelic.Profiler.dll
   NewRelic.Agent.IL.dll
   NewRelic.ICSharpCode.SharpZipLib.dll
   NewRelic.Json.dll
   NewRelic.Log.dll

   コピー

8. If you do not find any assemblies, get support at support.newrelic.com

Verify that the w3wp.exe environment details are this:

COR_ENABLE_PROFILING=1
COR_PROFILER={71DA0A04-7777-4EC6-9643-7D28B46A8A41}
NEWRELIC_INSTALL_PATH=C:\Program Files\New Relic\.NET Agent\

Check for profiler logs in %ALLUSERSPROFILE%\New Relic\.NET Agent\Logs.

• Make sure there are no profiler logs for the web app you are troubleshooting.
• If you have a simple or default site installation, ignore any profiler logs for other web apps.

If all the above conditions are present, you have a permissions error. Use any of these options to resolve the permissions error as applicable:

C:\Program Files\New Relic\.NET Agent\

C:\Program Files (x86)\New Relic\.NET Agent\

$key = "HKLM:\SOFTWARE\New Relic"
$acl = Get-Acl $key
$AddACL = New-Object System.Security.AccessControl.RegistryAccessRule ("Everyone","FullControl","ObjectInherit,ContainerInherit","None","Allow")
$acl.SetAccessRule($AddACL)
$acl |Set-Acl -Path $key
