Sen2Cor 2.3.1 does not work


I have been struggling with the Sen2Cor 2.3.1 installation. OS Version, Windows 10. Installed pacakges, Anaconda2-4.2.0-Windows-x86_64. When running Sen2Cor 2.3.1 installation via python install, installation runs then removes Glymur and does not go any further.

Forcing to stop then testing, it complains Glymur is not install, then I install via pip install Glymur.

in theory, this means that the L2a processor should now work, when I try the conversion on any resolution, it fails. See below, any assistance would be highly appreciated.

Manage to resolve, issue is with Package - file
