Version 7.0.0 Release Notes


Previous Release

Version 7.0.0 was released in August 2020 and has been succeeded by newer versions.


Before installing this version, your Tricerat Licensing Server must be upgraded to v5.3.1 or later!  The upgrade to v5.3.1 Tricerat Licensing Server needs to be completed before upgrading any server session agent to avoid license checkout issues!  See this page for upgrade instructions: Upgrading Your License Server  The latest version is v5.3.1.

Version 7 products are not compatible with version 6 activation codes. You will need new activation codes for version 7 products. Please contact your Salesperson for more information.


Before installing this version, you must install the .Net 4.8 Runtime. Failure to do so will prevent license activation of a nodelocked license and all UI will fail to run as it is dependent on this version of .Net.


There are several items to keep in mind for those upgrading from v6:

  • If you need to stage your upgrade into smaller steps the first step will be to upgrade your Print Server agents first. v7 Session Agents cannot communicate over non-TLS connections to the older Print Server agent. If you are using v6 Proxy agents they should be upgraded to the v7 Connector next. After that you may upgrade your DB and Session Agents to v7 as you can.

  • To upgrade your DB you will need to run once (and only once) the new ScrewDriversDatabase installer. This will handle updating the DB schema to support the new features. Note: This will also introduce the new authorization data into the database. The new ScrewDrivers Administration settings application by default can only be run by Domain Admins and Local Admins from the machine where the ScrewDriversDatabase installer was run as well as the user who ran the installer. Any additional users will need to be added from within the Administration application.

  • ScrewDrivers and Scanning clients are both forward and backward compatible between v6 and v7 servers however this is with current settings only. The backing registry locations for settings have been moved and a v6 client that downloads a v7 plugin via auto client update cannot place settings where the v7 plugin expects them and vice versa. To get full functionality you will need to upgrade clients to v7.

Product Refocus

New Features and Enhancements

  • The Simplify Console is now ScrewDrivers Administration and has had a complete overhaul!

  • Every UI element have been redesigned and updated across all products.

  • Security has been updated: We use a TLS 1.2 enabled database SQL driver and all ScrewDrivers socket based communications are TLS 1.2 enabled as well.

  • A new installer, ScrewDrivers Database, is included to allow your DBA to create or update your Tricerat SQL database. This allows the ScrewDrivers installers to run with reduced/normal SQL database permissions when updating session agents.

  • ScrewDrivers clients have expanded:

    • New Linux client supports RDP, ICA and PCoIP protocols

    • MacOS client now supports RDP PCoIP in addition to ICA protocols

    • New Windows client that uses TCP sockets instead of virtual channels. This enables support for HTML5 client implementations.

Improvements and Fixes

  • All UI’s re-worked for consistency and functionality.

  • ScrewDrivers Endpoint option to only add clients default printer has been fixed.

  • ScrewDrivers Endpoint Pro option to add denied drivers has been fixed.

Deployment and Platform Changes


  • All support for any 32bit OS has been dropped.

  • All support for Desktop OS’s prior to Windows 10 and Server OS’s prior to 2012 R2 have been dropped.

  • .Net 4.8 Must be installed prior to any Version 7 installer. Because it is no longer installed as a Windows Feature it cannot be included directly in our installers as a pre-requisite.

  • All high-permission requirement database actions (create, init and update) for Pro and Enterprise are moved to a separate installer that is run once per environment. This installer is called ScrewDriversDatabase_<version>_x64.exe. The main installer ScrewDriversProOrEnterprise_<version>_x64.exe now only requires basic read and write access to the Tricerat database.

  • Authorization for ScrewDrivers Administration is now built in as a core feature. This feature gets initialized when running the ScrewDrivers Database installer. Initially Domain Admins, Local Admins for the machine where the installer is run and the user running the Database installer will be Super Admins. From there you can give out permissions to other users via the Permissions tab in ScrewDrivers Administration.

Known Issues

  • The ScrewDrivers Client has a slow printing performance issue when using Citrix Workplace version 2006 on the Linux OS. This will be addressed in a future version.

  • The ScrewDrivers Client may have permissions issues when using the macOS and RDP protocols. This will be addressed in a future version.
