Tacx deprecated TTS4 in 2019 as they moved to their cloud-based RLV trainer software, TDA. While TDA offers some great features and superb video experiences, TTS4 still provides some value for those who had built up extensive libraries of videos, use the local-LAN multiplayer features and Zwift-like VR worlds.

Tacx have discontinued support of TTS4 and decommissioned the license server. Meaning new installations cannot be registered. Pre-2020 registered users, can continue to use TTS, but should back up their license files in case of future issues. If not, you will not be able to reinstall the application.

The following features in TTS 4 will no longer work:
– License activation/deactivation;
– Online multiplayer;
– use of Google services (maps, street view) during GPS rides;
– BikeNet

My TTS4 gets stuck at startup

Generally TTS4 gets stuck during startup, as it reads all the saved rides. This can be remedied simply by doing some basic housekeeping. Move or Copy any important rides to another location and delete the contents of the following folders:

C:\ProgramData\Tacx\TrainerSoftware\TTS4\Trainings\Catalyst\Runs
C:\ProgramData\Tacx\TrainerSoftware\TTS4\Trainings\Ergo\Runs
C:\ProgramData\Tacx\TrainerSoftware\TTS4\Trainings\RLT\Runs
C:\ProgramData\Tacx\TrainerSoftware\TTS4\Trainings\RLV\Runs
C:\ProgramData\Tacx\TrainerSoftware\TTS4\Trainings\Tests\Runs
C:\ProgramData\Tacx\TrainerSoftware\TTS4\Trainings\VR\Runs

My TTS4 VR freezes with a blue screen!

This can happen when the versions of the two TTS4 executable files do not match.

To check the versions:
– Right click on the TacxVR.exe in C:\Program Files (x86)\Tacx\TacxTrainersoftware4\TacxVR\ and select ‘Properties’ and click on the ‘Details’ tab
– Right click on the TrainerSoftware.exe in C:\Program Files (x86)\Tacx\TacxTrainersoftware4\TacxVR\ and select ‘Properties’ and click on the ‘Details’ tab

If the versions do not match, you will need to reinstall TTS4.
