Critical updates for PAST5 and OSM4 (October 10th, 2016)

Prior to the latest build (600 for PAST5, 1002 for OSM4), both PAST5 and OSM4 sometimes consume CPU cycles unnecessarily. The latest update brings down the CPU usage for both programs in idle mode. Please download and install from here.

Issues with PAST4 and Windows 10 (December 21st, 2015)

Several customers reported instabilites when running PAST4 on the most actual Microsoft operating system, Windows 10, especially on 64-bit systems. We are currently trying to figure out the cause for this issue and if possible, will present a fix. However, please keep in mind that PAST4 is a retired product and will not see any major further development. We suggest to upgrade to PAST5 at your convenience and therefore have extended a special upgrade period until April 30th, 2016. To receive a quote for an upgrade, please contact us by email.


N.B.: Licensed Users with a PAST4 USB key may run PAST5 with all features enabled for 20 times. Updating from a PAST4 to a PAST5 license can be done electronically. See here for information on upgrading existing PAST4 licenses to PAST5. To receive the upgrade, please contact us for a quote.
