Can I use 32-bit software components on a 64-bit operating system? 32-bit software components may generally be used on 64-bit operating systems, where the operating system and hardware support 32-bit components. Virtually every 64-bit Mac or Windows environment supports both 64-bit and 32-bit software components.Exceptions include early Itanium systems, which only supported 64-bit software components, and 64-bit Linux environments which lack the 32-bit "shim" libraries necessary for 32-bit support.Our 32-bit components may be used with 64-bit databases for which 32-bit client libraries are available, or where database-native client libraries are not required (e.g., MySQL, PostgreSQL, Microsoft SQL Server, Sybase).
