Crystal Reports for Visual Studio 2005 projects can be built on a 32-bit or a 64-bit machine. In addition, the projects' code can be ported to and updated on a 64-bit machine. Itanium (IA64) processors are supported for run-time only.
On a 64-bit machine, the 32-bit Crystal Reports for Visual Studio 2005 IDE will run under WOW64 (the x86 emulator that runs 32-bit applications on a 64-bit machine).
Before you can run an application on a 64-bit machine you must install the Crystal Reports 64 bit configuration application for your 64-bit environment.
If you have installed Visual Studio into the default installation directory, the configuration application can be found in the below directory.
