When can we download a 64bit windows 7 version?

Question

I couldn't find the answer to this by searching. When is a 64bit version available for windows or is there instructions on how to compile it using microsoft visual studio 2010 or some freely available compiler on windows 7? It is critical to be able to use more memory that 64 bit can address. I am ready to switch to using this viewer when it is available on 64bit windows.

Answer 1

There are no plans yet to provide a native 64-bit Windows version. However, the normal 32-bit Windows version runs fine on 64-bit Windows, and has been compiled to be "large address aware", which allows it to use large amounts of memory if your system supports that.

Answer 2

To compile a native 64-bit viewer, you'd have to get 64-bit versions of the required libraries in place. For Windows, 32-bit library binaries are downloaded automatically during the build. Replacing them locally by their 64-bit counterparts might be a non-trivial task.

I also guess the Windows-specific parts of the source code might not work correctly when compiled for 64 bit, as they were only tested for 32 bit builds, yet. (Some code might even explicitly assume 32-bit specific conventions.)
