In the case that a client and server are on different architecutres (32 bits/64 bits), the discrepencies between the 32bit/64bit components and tools will stay consistent with the client's architecture.

One example, the Quick Report Tool is different between 32 bits and 64 bits. This is the 64 bits Quick Report:



This is the 32 bits Quick Report:



A client on 32 bit will load the 32 bit Quick Report Tool and a client on 64 bit will load the 64 bit Quick Report Tool. This is the behavior regardless of which architecture the server is running on (32 bits/64 bits).
