Big Problem production machine CR12

Hi all,

I have a web project in which I have CR12 integrated with Visual Studio 2012 and Framework 4. On the development computer works fine, but when I want to publish my application on a server, the report is not displayed. It does not give any errors or anything, just shows the container but not seen information.

I installed all the runtimes for 32 and 64 bit and nothing.

The server has the following characteristics:

Windows Server 2008 R2

IIS7

Framework 4 and 4.5

Any suggestions?

Thank you very much.
