Hyland Software recommends the 64-bit Application Server for most installations. However, a 32-bit Application Server must be used for systems with Unity Scripts that reference custom, 32-bit-only, native libraries or a 32-bit-only Microsoft .NET Framework DLL. For information on updating these 32-bit resources and the Unity Scripts that reference them, contact your first line of support.
For more information on the differences between a 64-bit and a 32-bit Application Server, see the Application Server module reference guide.
