You can educate your users that they can also install side-by-side the 32bit JVM. All windows 64bit system support WoW64 and therefore the 32bit JVM and 32bit windows application space. Qt Jambi does work on Win64 in both MSVC and mingw-w64 forms, if you really care you just need to compile it yourself (i.e. if it was that much of an issue/problem you would find the time to be able to compile it yourself). > For this it would be extremely helpful if we could make this transparent > for our users: i.e. being able to use Qt-Jambi, regardsless of the fact > that you have a 32-bit or 64-bit JVM installed. > > Unfourtunately I couldn't find binary distributions yet for Windows on > 64-bit (amd64). Are there plans for building Qt-Jambi on 64-bit for Windows? The only way to get "transparency" is to allow BOTH the win32 and win64 JARs to be placed on the Java classpath at the same time. This would (in the future) require you to download BOTH flavors of redistributables and shallow the problem of increased installation size. Please note this feature is not possible at this time as QtJambi will complain on startup and get confused when multiple JARs are present. But the general concept of this feature is being worked on and is expected to be a feature available before the end of this year along with OSGi and some support for Eclipse tooling. Yes there are currently no redistributables for windows 64bit at this time. But the git source tree will build for Windows 64bit (if you have a 64bit version of Qt SDK to work from, which you may need to build yourself as well). There are only 2 remaining show stoppers with releasing 4.7.4-beta-4: * That the Win32 MinGW build crashes on startup of the Launcher. * That the examples/generator/hello_world_generator crashes on startup on all platforms I tested, Linux64, Win32. Although another user has reported that current git master (the same version I tested) works for them on msvc2008 and win32. Both of these things require a proper explanation as to the problem and then feedback/corrective action into the project to help test for the cause which then stops it from being a problem again. This 4.7.4-beta-4 release will provide redistributables for win64 in both MSVC2010 and mingw-w64 flavors.
