Is there a Hexagon x64 available? Can't find specifications. Thanks.
No, but you can use the 4Gb Patch available here http://www.ntcore.com/4gb_patch.php
It will allow Hexagon and other 32-bit apps to use more than 2Gb of RAM in a 64-bit version of Windows, and is limited to 4Gb regardless of installed RAM.
It worked perfectly! Thanks a lot.
