But when the extension ends with win32, you can see that asking for confirmation from users using win8.1 64bit
Point taken.

For the record, just in the case of any program, 32 bit programs work on 64 bit windows, however 64 bit does not work on 32 bit.
Microsoft includes the 32 bit libs for backwards compatibility and such.
what software do you use?
I don't shoot in raw, but the tests I have done I use that MlRawViewer to view it.
However I am on ubuntu (gnu/linux) 64 bit, and I build/run it from source.
(In addition to I have contributed slightly to the source, only minor things, nothing close to the work that baldand has put in).
Thanks.
No problems. (Despite my sassy attitude
