Not able to launch login window in ARAS 10

Hi,

I have installed ARAS 10 in my windows 7 machine. It is installed successfully without giving any warning.

I have run the .NET framework and .NET security also.

I am not getting the login window when I click on "ARAS" icon created on desktop by installer. Instead I am getting below error-

HTTP Error 500.21 Internal Server Error

Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list.

Thanks,

Manali
