You may need to know your the version and build number of your GeoExpress software in order to communicate with LizardTech Support. To find these numbers, use the ‑version
switch as follows:
mrsidgeoencoder -version
This will return several lines that may look like this:
Using commuter license issued from server: 10.0.17.5
Version 9.5.5.4567.default (64-bit) (Nov 15 2017, 03:14:16)
In this case, the version number is 9.5.5 and the build number is 4567.
