Support is no longer available for MSEW(3.0) or ReSSA(3.0). Users of MSEW(3.0) and/or ReSSA(3.0) are advised to upgrade to MSEW+ and/or ReSSA+. Such an upgrade requires purchasing a license for the standalone MSEW+ and/or ReSSA+ programs.
Owing to changes in operating systems and associated security constraints, we are no longer able to ensure that ReSlope(4.0), GeoCoPS(3.0) or FoSSA(2.0) purchased prior to 2020 will remain fully operational. As a result, these programs issued prior to 2020 are no longer supported. If interested, you may purchase the updated software and its associated driverless keys. See revised price list in the Order section.
