Hi mojde,

You've posted your question in the ASP Forum which is for Classic ASP only - I've moved it for you but in future please post all ASP.NET questions in the .NET Forum.

Thanks and regards,

I suggest you get support from the publishers of FastReport. It is very unlikely that one of the experts here has experience supporting that specific 3rd party software.
