Re: Can't setup Trezor hardware wallet.

Version 2.4.2 was released today, with OSX and Windows binaries.
See https://electrum.org/#download

However, hardware wallets (trezor, ledger) are not supported in the current Windows binaries.
If you use a hardware wallet, please wait until we have better binaries.

Try to use another Operating system (Linux or Mac) and try since he said only Windows binaries .

Thanks. Guess that explains it. I will have to use an alternative for the time being.
