Enable 32-bit application pool mode on a 64-bit server

We have it 64-bit Windows server, and we need to explicitly enable it 32-bit modein the application pool used by our website because it MS Jet Engine Data Provider used to import data from Exceldoes not work.

I'm not sure if we turn on the mode 32-bit, we still get the advantage of 64-bitServer?

IIS 7.x has the Advanced Settings property of the Enable 32-bit Applications pool of applications. If you run the application in the form of 32-bit applications, it should be able to use 4 GB, but, obviously, nothing more. Thus, in this regard, he can take advantage of working on a 64-bit server. On a 32-bit server (without special switches), it will be able to use only 2 GB of address space allocated for applications (the other 2 GB is supposed to use the OS).
