Error profiling an ASP.Net application

adrianbanks

When I press the Go button to start profiling an ASP.Net application, I get an error message:

There was a problem starting the profiler. Check that the ANTS Profiler service and IIS are running.

Exception from HRESULT: 0x80040202

The entry in the event log is:

System.Runtime.InteropServices.COMException (0x80040202): Exception from HRESULT: 0x80040202
   at System.Runtime.InteropServices.UCOMIConnectionPoint.Advise(Object pUnkSink, Int32& pdwCookie)
   at SHDocVw.DWebBrowserEvents2_EventProvider.add_OnQuit(DWebBrowserEvents2_OnQuitEventHandler )

   at RedGate.Profiler.UI.frmMain.ᐐ()
   at RedGate.Profiler.UI.frmMain.ᐑ()
   at RedGate.Profiler.UI.frmMain.ᐁ(IAsyncResult )

I'm using version 1.30 build 147 and I have version 1.1 and 2.0 of the .Net Framework installed.


How do I fix this?

Just found an old post on here with similar issues. Seems to be an issue with IE not being registered properly.

I've got around it for now by reinstalling IE.

Hello Adrian,

This could be. If you have a newer version (2.1+), then ANTS tries to re-register the InternetExplorer dll automatically and if it can't, it yields a slightly different error message.

If you have a lesser version, you need to run regsvr32 shdocvw.dll.
