Download page for Prolog Version 4

It is the release version. However when downloaded it runs in demonstration mode. In this mode the following restrictions apply

• graphics print out - only first 10 entries are printed
• output to dwg file - only first 10 entries are displayed
• data transfer to other systems - only first 10 entries are exported.

If you need to trial a version without any restrictions - download the version as is. If you then send us an email with the site code; we can enable the software via email for a time limited trial run.

If you purchase the software we send you a hardware lock that plugs into a USB port on your computer.
