I just found out about TMS Smart Setup (and it is everything I wanted, thanks for creating it).
Aftering reading on some other threads here, I understand that I should first unisntall any package that I want to install via the new installer. I also read that not all packages are available in the installer (as of oct 2023).
Is it correct that these packages are not available in the new installer?
Correct, those products are not yet in TMS Smart Setup.
Eventually (sooner than later) all TMS products will be available in TMS Smart Setup anyway.
Currently you can quickly check what's available in Smart Setup by issuing the tms list-remote command, os simply opening the TMS Smart Setup GUI tool and seeing the available products there.
