ET GeoTools 11.3 and ET Surface 6.2 are
available in six sub-versions with exactly the same functionality:
The latest versions of all products are extensively tested and perform equally well on all ArcGIS versions 10.0 and above, including ArcGIS 10.5
ET GeoWizards 11.3, ET GeoTools 11.3 and ET Surface 6.2 are extensively tested on ArcGIS running on Windows XP, Vista, 7, 8, 8.1 and 10 ( 32 and 64 Bit).
We a striving to provide support to all ArcGIS users, no matter of the version of ArcGIS they are using. Our records show that the number of ArcGIS users that still use ArcGIS 8.x, 9.0, 9.1and 9.2 significantly decreased over the last couple of years. This and the huge effort needed to maintain too many versions of each product, together with the enhancements of ArcGIS that cannot be used on the older versions forced us to drop the support of our software for ArcGIS 8.x, 9.0, 9.1 and 9.2
Note that a license of any product of ET SpatialTechniques is valid for all sub-versions of this product and comes with one year free maintenance and upgrades. If for example you are currently using ArcGIS 9.3 and purchase a license of ET GeoWizards you will need to use version 11.2 (this is the last version compatible with ArcGIS 9.3). If you however upgrade to ArcGIS 10.4 six months later, you can upgrade free of charge to ET GeoWizards 11.3 .
