When you click Start Profiling for an AS= P.NET web application (IIS), profiling may not start, and a "Cannot start I= IS" error may be displayed. This can indicate that:
This page describes how to fix these issues.
ANTS Performance Profiler starts the IIS applicatio= n pool with permissions inherited from the currently logged-in use= r account, rather than using the IIS application settings.

The error may also occur when using "Manually speci= fy ASP.NET account details". Check that the specified account is a valid us= er, has administrator privileges, and has read access to %ProgramFiles%\Red Gate\ANTS Performance Profiler 8\RedGate.Pro= filerCore.dll and %ProgramFiles%\Red Gate\ANTS Performance Profiler 8\X64\RedGate.Pro= filerCore.dll
If the bindings in IIS have been changed from the d= efault, ANTS Performance Profiler may be unable to resolve your site's host= name. This error message may be shown:

This is usually caused by enabling line-level timings with code using th= e SecurityTransparent attribute. For more information, see Profiling SecurityTransparent and partially-trusted assemblies<= /a>.
IIS can fail to start if ANTS Performance Profiler = encounters a conflict with another performance profiler.

You= can tell if another product is profiling IIS using the free Microsoft Proc= ess Explorer (download here):= p>
If you had ANTS Performance Profiler version 7.0 an= d installed the early access build of the continuous profiling tool, an IIS= module installed by the continuous profiler may be preventing profiling. T= o re-enable other profilers with IIS, uninstall the IIS Profiler Module:
