# How can I find out whether I have 32bit or 64bit of MiKTeX installed?

I am trying to debug a problem with biber not being available. I know it's not in 64bit. So I need to find out what the machine's installation of MiKTeX has.

Well, great! I just found out that it's 64bit. It seems ProTeXT in all it's wisdom installs 64bit version of MiKTeX!!! That's the last time I'm using that –  drozzy Feb 21 '14 at 19:15
One option: if the miktex path is `C:\Program Files (x86)\MiKTeX 2.9` then it's 32-bit and if its `C:\Program Files\miktex 2.9` then it's 64-bit miktex. Related How can one install biber on miktex 64-bit? and MikTeX x86 vs MikTeX x86_64 –  texenthusiast Feb 21 '14 at 19:46
Thanks, you should make this into an answer. It is indeed true, that paths are different and reflect the architecture type. –  drozzy Feb 21 '14 at 19:52
Please self answer (as its acceptable) since you already found the answer first and add some of my details if you wish. –  texenthusiast Feb 21 '14 at 19:54

1. If the miktex path is `C:\Program Files (x86)\MiKTeX 2.9` then it's 32-bit and if its `C:\Program Files\miktex 2.9` then it's 64-bit miktex
