Sorry for the delay. It took a little longer to fix it. The python script should work under WINDOWS without problems (LINUX not operational at the moment). 
script.zip (5.1 KB)
Run the script in the command window:
>
python C:\...\examples\run_sen2cor.py <S2_L1C_Collection_in_path> <resolution> <S2_L2A_Collection_out_path>
Parameters:
<S2_L1C_Collection_in_path> : Mandatory, e.g. C:\S2-Collection
<resolution> : Optional, Default = 10
<S2_L2A_Collection_out_path> : Optional, Default = <S2_L1C_Collection_in_path>
Cheers,
Andreas
