Hello @snaojee @barala,
After trying every possible solution, I finally could make it work. However, I am unsure whether it is the best possible solution, and I did not validate the results. So be aware!
What I did was to copy the all the context from:
C:\Users"YOUR USERNAME".snap\auxdata\Sen2Cor-02.08.00-win64
and paste it to
C:\Users"YOUR USERNAME"\Documents\sen2cor
In addition to that, you may also want to try the solutions provided on:
It is also worth noting that, unlike the SNAP software, which is capable of reading images as ZIP files, the Sen2Cor module has some difficulties reading ZIP files, so it might be better to extract the files and select the metadata (MTD_MSIL1C.xml) as the input.
Yet, if all of those didn’t work, you still have the option to run the stand-alone sen2cor program, but that might be cumbersome because of all the codings in cmd.
