the machine in which my application is installed is a server machine(running on Windows Server 2008 R2 SP1) and it is as u can guess running on the 64-bit OS.
Navigate to Server Manager > Roles > Web Server (IIS) > Internet Information Services (IIS) Manager, then look under your machine name > Application Pool
Under there you can call the DefaultAppPool’s advanced settings to change Enable 32-Bits Applications to True
You may have to restart the service for it to take effect but it should work
