IsoDraw 7.1 M30 is fully supported on Windows 7. There are no issues revising IsoDraw illustrations created in any of the earlier versions using IsoDraw 7.1. You can also save backward if required; however, we always recommend saving in the current version.
If you’ve got active maintenance, you can always find system requirements and support information at PTC.com > Support > Product Support Centers > Arbortext > Related Resources – Help Centers > Arbortext IsoDraw.
Expand Arbortext IsoDraw and you will find current release notes in PDF. Near the top of the IsoDraw 7.1 M30 Release Notes you will find the system requirements. For those on older versions of IsoDraw you can learn about new capabilities here as well.
One last thing for people on active maintenance: we recommend you review your account settings. You can be notified whenever there are product updates.
