there is no need to have GPG software installed in order to use the desktop version of Trezor Suite. You can use Trezor Suite for desktop if your OS meets these requirements: https://trezor.io/learn/a/os-requirements-for-trezor
Please note that you need Trezor Bridge installed on your computer for the web version. You can download it from this source: Trezor Suite
(use supported browsers for the web version of Trezor Suite - Chrome and Firefox)
I would also like to mention that using of Trezor Suite is not mandatory, you can use your Trezor device with 3rd party apps that support Trezor devices. However, using Trezor Suite is recommended.
ok very good. Thank you for clarifying.
My version OS meets requirements so I will use Trezor Suite desktop version.
I found the GPG to be super confusing so I will disregard.
