PTGui runs on Microsoft Windows (Windows 2000, 2003, XP or Vista) and Apple Mac (OSX 10.4 or later). At least 1 GB free disk space (for temporary files)
is recommended. PTGui has been optimized for stitching large panoramas; despite the amounts of data involved with photo stitching,
PTGui runs fine with only 256 MB of RAM.
