Assume there is a computer running Windows 7+. I have an external drive with a bunch of portable programs, among which there happen to be two directories with complete portable versions of MiKTeX and TeX Live for Windows (each is nearly 6 GiB in size).
Can I perform a full install of either TeX distro on the standalone computer having
- minimal installer executables (say,
- files of the full portable install of both distros,
- no internet connection?
I tried to point newly installed MiKTeX package manager to the location of the existing portable installation, unsuccessfully:
With TeX Live it looks like one has to use a mirrored repository exclusively, however I haven't found any evidences that portable installation cannot be used instead.
I'm aware that I can just copy files to the local computer and set the $PATH to something like
C:\TeXLive\2018\bin\win32, but I would like to know for sure whether there is a chance to use a portable version as a local repository.
