OPUS devices update manual > Contents of the software update

The ISO-VT program consists only of one file:

user.tar.gz – zipped package with PClient and VT (virtual terminal) executable, additional files and ISO-VT settings project (user_opusax_2.x.tar.gz for OS 2.x, user_egspro_x.x.tar.gz for EGSPRO OS)

Additionally there is an md5 checksum file for this file which is used to check the integrity of the files in the installation.

In Windows, the user.tar files are often shown as zip files. Never unzip these files or the update won't work!
