I filed RFE #6874788 on this question.  It should be visible outside Sun
in a few working days.

Every .exe that uses MSVCR80.dll (Visual Studio 2005) or MSVCR90.dll (VS 2008)
must deal with .manifests, side-by-side assemblies, and so forth.

It is not too hard to get it working on your development machine by installing
Visual Studio, or installing the redistributable runtimes (vcredist_x86.exe) [1]

It is when you try to share your work with others, or transplant it to a test
machine that the executables will fail to run.

We can't ask everyone installing a JRE or JDK on Windows to install [1] first.
That would be a barrier to adoption.  So I am working towards getting our
installer to create what Microsoft calls a 'side-by-side' assembly and install
that on the client machine if it is not already there.

BTW: Our current releases work because they put a copy of msvcr71.dll into
C:/WINDOWS/system32/.  This trick was always vulnerable to having the file
replaced or deleted by some other application or installer.  The option
has been specifically ruled out by Microsoft for the newer runtimes.
