Compatibility: Steinberg Applications and Microsoft Windows
Vista/7 32-bit and 64-bit Versions
Microsoft Windows Vista and
Windows 7 operating systems are available in two versions: the 32-bit and
64-bit edition. The main difference between these versions is the size of RAM
that can be addressed by the operating system and applications.
Windows x86 (32-bit) version
A 32-bit operating system like
Microsoft Windows Vista allows you to run 32-bit applications only, while each
application can address up to 2 GB of the available RAM. Generally, all
Steinberg applications are available as a 32-bit binary and can be run with
32-bit versions of Microsoft Windows Vista and Windows 7.
The 64-bit versions of Microsoft
Windows Vista and Windows 7 let you run 32-bit as well as native 64-bit
applications such as Cubase 6 or Cubase 6 x64. Thanks to the OS built-in
compatibility layer that allows 32-bit software to run on 64-bit operating
systems, all Steinberg 32-bit applications supporting 32-bit versions of
Windows Vista and Windows 7 are supported on 64-bit operating systems as well.
The difference is once again the amount of RAM available to applications.
While a 32-bit application running on a 64-bit operating system can address up
to 4 GB of RAM, (which is already twice as much as under a 32-bit version of
Windows), a native 64-bit application such as Cubase 6 x64 supports a much
larger RAM capacity.
For many of its products,
Steinberg already provides both 32-bit and 64-bit versions that are found on
the same installer disc. This allows you to choose which version best fits
your current requirements. Please note that if your installer includes the
32-bit version, but not the 64-bit version (such as Sequel), your product does
support Microsoft Windows Vista 64-bit / Windows 7 64-bit versions but is not
able to access more than 4 GB of RAM at a time. If a native x64 application is
also included, the system requirements on the corresponding Steinberg product
page mentions that a native x64 version is included.
Please note that there are
further differences between the 32-bit and 64-bit versions of Steinberg
applications. For example, some components may currently not be available in
64-bit, such as QuickTime and Rewire. Generally, 64-bit VST hosts won't be
able to run 32-bit VST plug-ins, but only native 64-bit VST plug-ins. However,
Cubase 5 x64 can also support 32-bit VST plug-ins thanks to VST Bridge
technology from Steinberg, which allows 32-bit VST plug-ins to run in a 64-bit
host environment, Please note that compatibility issues may still occur owing
to technical limitations in the bridging process. These limitations do not
affect running 32-bit Steinberg host applications under Microsoft Windows
Vista/Windows 7 64-bit versions and affect only native x64 host applications.
