gCADPlus installs in about 50 Mb of disk space and makes very little demand on computer resources. Any modern computer capable of running Windows should be suitable although the more main memory installed, the better. We have run gCADPlus successfully on Windows XP, Windows 7, Windows 8.1 and Windows 10 computers.
It is also possible run gCADPlus on Mac computers. We recommend installing CrossOver so gCADPlus can run on the Mac. CrossOver and gCADPlus are free to try. Here are some links giving more information about using gCADPlus on Macs.
