I manage to solve my problem. I had to uninstall everything, including Anaconda and SNAP. I re-installed everything again following exactly the instruction, including the part where Anaconda is python 2.7 default (which by the way made my QGIS inoperable).
The same black window appeared. I then confirmed all paths in the edit SEN2COR tollbox and the SEN2COR_HOME path was not correct. I changed to the default.
After that I still come across with an error in the SEN2COR processing window. It turns out there was a wrong path in the Anaconda2\lib\site_package\sen2cor-2.2.1-py2.7.egg folder. The folder cfg was not there but inside another folder sen2cor. I’ve copy cfg folder and put it inside sen2cor-2.2.1-py2.7.egg and now it is working, including processing 10m images.
I hope it helps.
I have a similar issue however it is not resolved by the above fixes. I am running the program on Windows 7. I had a similar issue with the wrong path for the \Anaconda2\Lib\site-packages\sen2cor-2.2.1-py2.7.egg\sen2cor, I then copied this to here: \Anaconda2\Lib\site-packages\sen2cor-2.2.1-py2.7.egg and this time command prompt states the program has started but does not do anything. When run through SNAP the issue that the display window remains totally black and nothing happens.
I have now tried all the above, including moved directly to C: to reduce filenames and created a PYTHON_BIN as a system variable. Are there any other potential solutions?
You must keep short the name of the selected input product including the path. Copy your L1C-file near to the root-directory of your drive. Keep ‘S2A_OPER_MSIL1C’ of your input file. I delete/rename the acquisition time which is doubled at the end of the filename coming to product file name like ‘S2A_OPER_MSIL1C_R065_V2015-08-06-T1020.SAFE’. All what I deleted is kept in the name of the xml in the root directory of the L1C-product which I don’t change.
