Crystal Reports .Net 4 Beta 2 Production Exception

I have an application that generates some pretty basic reports. I have installed the crystal reports .net 4 beta 2 for visual studio 2010 and copied the DLLs into my web site's bin folder. Everything works fine when running locally but when I try to create a report on my production server I get the following exception thrown.

Retrieving the COM class factory for component with CLSID 
{C0D87D96-8D57-4274-AA18-D465E31F901E} failed due to the following error: 
80040154 Class not registered (Exception from HRESULT: 0x80040154 
(REGDB_E_CLASSNOTREG)). 

And here is the stack trace:

I haven't done a whole lot with crystal reports so there may be something I am missing, but I had to manually copy the DLLs from my GAC into my applications bin folder because I didn't want to run the installer on production. Everything worked locally when I removed the dll loads from my web.config so my site would look in Bin for any additional dlls but I don't know why it is going wrong.

Anyone have any insight?

EDIT:

I also have installed the runtime for deployment on the server as well to see if that was an issue.

Well after contacting the crystal reports users on their forums it looks like you can only have the .net 4 runtime installed on your production machine, as this was unfeasible for me I had to migrate down to 3.5 to get everything working.
