Install 3.30.7.0 - Error

[JKaye_1@charter.net]

I deleted the previous Trainer, since it said it was already installed. Downloaded the file Garmin Trainer Setup_3230.exe.

Then ran this setup.exe file. Success installing Trainer v3.2.3 and Database 3.2.1.

Started installing GTN Xi (20.20.10), but then there was an error. Tried both options - Recreate aircraft and then Reload aircraft. Said - Install 20.20.10.0 - Internal Error. Please retry, and report this if it continues.

Available Version 20.20.10.0 was displayed, but the option to Install was not displayed.

Error Details were as follows:

Summary: GTI exited with a failure code.

Complete Error details:
- Catalog installation failure detected. Please restart the Launcher.
- GTI exited with a failure code.

So apparently Version 20.29.10.0 will not install.

Also, under Avionics, Multi-Engine Piston it says: An error occurred while displaying this aircraft.

Error Details
Catalog installation failure detected. Please restart the Launcher.

I really appreciate your help but need advice on how to proceed.
