Google doesn't know what "Nano Command Prompt" is, so you may need to define your terms. But I'm assuming you meant Windows Nano Server.
That OS lacks GUI components and the ability to run 32-bit apps, both of which are required for Inno installers even if you try to run silently and with a script targeting 64-bit OSes only.
Besides, Microsoft did not include MSI in that either; while this is not a requirement for Inno, it does suggest that they intend apps to be installed very differently from traditional desktop installers like Inno.
