How does UaDriver operate in the 64 Bit Windows environment?
Although the UniAccess ODBC driver is a 32-bit application and has not been tested on a 64-bit Windows platform, our research indicates that it should be compatible in many environments. The underlying factor in determining the interoperability with the 32-bit UADriver is whether application is 32-bit or 64-bit. If the application is 32-bit, it must use a 32-bit ODBC driver. Windows Server 2003 64-bit and Windows XP 64-bit can both execute 64-bit applications and existing 32-bit applications. 32-bit applications use “Windows On Windows 64” (WoW64) x86 emulator. Wow64 allows 32-bit productivity applications developed using the .NET Framework 1.0, 1.1 and 2.0 and Win32 to run on 64-bit Windows and take advantage of the 64-bit Windows kernel which offers a larger number of kernel handles and window handles. WoW64 emulation is performed natively (on the chip) by the x64 micro-architecture, which means WoW64 performance on x64 is similar to that of 32-bit Windows.
