Known Issues

For some types of application, you may have to run ANTS Memory Profiler as an administrator.

On Windows Vista and Windows 7, after profiling IIS using attach to process, ANTS Memory Profiler 6 sometimes cannot stop the session.  If this happens, restart ANTS Memory Profiler before starting a new profiling session.

In some cases, Windows Services do not restart properly after profiling. Use services.msc to restart services if required.

To profile an XBAP application, Internet Explorer must be set as your default browser and it must be closed before profiling.

To attach to a .NET 4 process, you must first disable concurrent garbage collection.
