Discontinued / Previous Versions

Earlier software versions and discontinued maintenance and support

With the release of MVRsimulation VRSG® version 7, we no longer sell or distribute earlier versions of VRSG. We no longer provide maintenance and technical support for VRSG versions 3, 4, 5, or for the retired software products WorldPerfect and Metadesic Compiler. The warranty period for the older versions of these software products has long expired.

In order to receive maintenance and technical support for any MVRsimulation software product, you must have active software maintenance for your license(s). Customers of the retired terrain generation products WorldPerfect and Metadesic Compiler must upgrade to the current version of MVRsimulation’s Terrain Tools for ArcGIS software with the purchase of active software maintenance.

Contact MVRsimulation sales for more information about your specific license agreement.

Prior to the installation of a new version of a MVRsimulation software product, you must remove of the previous version of the product from the system on which the new version will be installed.

Terrain database version support

All .hpx and .hpy 3D models that were distributed with VRSG versions 4, 5, or 6, or WorldPerfect are compatible with VRSG version 7 software.

Flat-earth .mdx terrain that was distributed with legacy versions of VRSG or WorldPerfect are not compatible with any VRSG version 7 software. VRSG version 7 supports round-earth .mds formatted terrain only. All .mdx flat-earth terrain databases created with WorldPerfect are not supported in any version of VRSG version 7. All .mds round-earth terrain created with version 2 of Metadesic Compiler can be rendered with any VRSG version 7 software license.
