Sen2cor [Errno 13] Permission denied

Hi guys, I’m trying to install sen2cor-2.3.1 on windows 10 (64bit)
I followed the instruction on [L2A-SRN] S2-PDGS-MPC-L2A-SRN [2.3.1].pdf document. I installed Anaconda2-4.4.0-Windows-x86_64, I check it as instructed and all seemed to work well. I enter in the folder sen2cor-2.3.1 from the Anaconda prompt, and run the command: " python install ".
The prompt show me:
running install
running bdist_egg
running egg_info
writing sen2cor.egg-info\PKG-INFO
error: [Errno 13] Permission denied: ‘sen2cor.egg-info\PKG-INFO’

How can I solve this problem?

thank you.

Having the exact same problem now - was this ever resolved?
