Garmin trainer installation issues

[rtvstudio]

Hello,
I wanted to reinstall the trainer for PC, but I always get error messages:

1.) "Could not find GTNXi PC Trainer, it looks like it is not installed, please reinstall from the TDS GPS Manager or contact support!"
When tried to reinstall:
2.) Installation failed - Failed to install the GTN Xi v(20.20) Trainer. See details below - Must specify a Garmin Trainer Installer Catalog (.gtic) file
3.) Failed Installing PC Trainer Depency! Current Version: Desired Version 20.20.10

Thanks for any support and feedback
Regards
