When checking which version(s) of windows are or are not supported on your AltiGen MaxCS server, please refer to the MaxCS ACC / ACM manual for your specific AltiWare version.  This note is intended to point out that AltiGen does not have 64 bit drivers for any of our telephony boards, EXCEPT for the Max4000 boards.

This means that while 64 bit versions of windows are appropriate for many MaxCS applications, such as softswitch, HMCP servers, application servers, etc. will fail to load the AltiGen boards.
