I noticed that MetaTrader 4 build 1170 says this: We remind you that support for older versions of operating systems, including Windows XP/2003/Vista, has been discontinued. The minimum acceptable OS version for the client terminal is Windows 7. I was planning on switching to Linux as base OS for MT4. The earlier MT4 versions where able to run on 32-bit Windows but now it appears it might be 64-bit Windows. It isn't clear at the Metatrader4 website. Is anyone using the MT4 version 1170 on Linux using Wine? If you are using Wine, is it the 64-bit version?
