Hi @ABraun
I couldn’t find where to run this solution, when I try, the process does not happen.
I’m using windows 10, it handled 20m and 60m but not 10m.
Thank you:)
Did you run sen2cor from the command line? And which command exactly?
command line didnt run, closed it
Sorry, I can’t help without a command or an error message.
cmd closes when i enter command line screen,
I can’t provide a solution as written at "Sen2Cor-02.05.05-win64 - AttributeError: ‘L2A_Tables’ Object has no attribute ‘_L2A_Tile_PVI_File’ 18 "
please test if one of them works: https://www.howtogeek.com/235101/10-ways-to-open-the-command-prompt-in-windows-10/
entereing L2A_Process.bat is not sufficient, you have to add the name of the folder you want to process as well. Actually, exactly this is given as three examples in the link above 
Somehow there is a problem with the data structure. Does this happen for all products or just this one? If so, can you please check if it was fully downlaoded?
Also, can you please move the S2 folder (S2A…) to a directory with a short path, e.g. C:\Temp\S2A… (don’t change the products top folder name), and run again?
problem is solved, thank you
Good! What was the solution?
I moved the S2 folder (S2A…) to a directory with a short path, “C:\S2A…”
Thank you @ABraun for your help:)
Great to hear that solved it 
Dear @ABraun ;
Atmospheric correction process is work good but ‘Readme…’ text doesn’t appear in this folders(process data-L2A) such as original data folders.
Is it problem or not?
Thanks:)
What Readme text are you referring to?
If you don’t need it, all fine.
I am mention to raw data (S2A_L1C…). This folder has text message ‘Readme…’ .
After atmospheric correction process, my transactions is;
Reprojection-Subset-Resample-Land Mask. But when I worked to Random Forest Classification, it never processes.
The same problem was reported here last week, please check: Rndom forest classification steps - #71 by daveadema
1 (raw data folder)-
2 (atmospheric correction folder)
3(atmospheric correction 10m)
4(atmospheric correction 20m)
5(atmospheric correction 60m)
all fine?
Yes, the readme file is not crucial for loading the data into SNAP
