As I said in comment your crystaldecisions.reportappserver.commlayer.dll is not copied / present on your server. So for this you have to manually copy the dll and paste into you Bin folder

To copy a DLL from visual studio project follow the steps

1.Expand your Project's References hierarchy (Project should not be in debug mod)

2.Right Click on Particular Dll (in your case crystaldecisions.reportappserver.commlayer.dll) and select Properties and set 'Copy Local' attribute to TRUE

3 Build your project. The Dll should be there in your BIN Folder.
