This article describes the procedure for installing Mini- and Micro-Ranger 2 software.

Before you begin, refer to the relevant user manual for prerequisites/hardware requirements and request of copy of the release notes for the software version that you will be upgrading your system to. Confirm your PC meets all the listed hardware requirements and also confirm the HPT and ESH firmware versions; if these require updating, this can be done at a later date.

Note: Be advised that Sonardyne software is only tested and approved using an English version of Windows® 10 operating system.
