32 bit and 64 bit
« on: December 22, 2012, 14:14:08 »
I use a 32-bit MC portable version across different computers. One of my computers I use is a 64-bit. While 32-bit MC works fine on the 64-bit machine, is there a strong reason for me to have the 64-bit MC on my 64-bit machines? Will I have some limitation if I use a 32-bit MC on a 64-bit machine? Thanks.

Well it depends on what you do and need. 32bit version works for the most parts. but there are some minor issues.

The difference is that Windows will redirect some parts of the filesystem and registry for 32bit program that run on 64bit OS.

But the biggest issue is with installed shell extensions (Programs that shows up in right click menu)
32bit programs on 64bit system will only show 32bit shell extensions and 64bit program will only show the 64bit shell extensions.
And by default many programs will only install 64bit shell extension on 64bit OS so you will not be able to use them when running 32bit version.

Also 64bit program can use more of the memory for cache and stuff, But that is normally not an issue.
64bit version is also little faster then the 32bit version running on 64bit OS. but not much.
