In order for AQTime to be able to profile your IIS application, IIS should be run under the Interactive User account. If IIS is running under another account, AQTime may not be able to profile your IIS application. So, every time you start profiling in IIS profiling mode, AQTime checks the user account under which IIS is running, and if this account is not Interactive User, AQTime displays this message to notify you about possible problems.
