Sen2Cor dificulities

I wanted to process sentinel2 level 1C data to level 2A using sen2corr but I am unable to get any results yet. I am not sure whether its processing it or not. I don’t see any status bar. The process status bar disappears fast and I didn’t get/know whether the data is processed or not. Any idea please . I am new to SNAP and I really want to learn it.
I appreciate your help


Sen2Cor is facing some bugs but soon it will be released a new version.
