Crystal Reports On Windows 2012 Server Log4net Error

I can run Crystal Reports fine on my local machine. But when I copy the code up to the server and hit the page, I get the following error.

Couldnot load file or assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=692fbea5521e1304'or one of its dependencies.The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) 

I installed the CRforVS_redist_install_64bit_13_0_15 since the server is 64bit. The Dev PC is also 64 bit and running the same library.

I copied the log4net version 1.2.10.0 to the bin folder and still have the error.

Any help or direction would be greatly appreciated.
