The L2A product with 10 m or 20 m resolution can't be opened in SNAP

Hi, sir.
I had used sen2cor-2.5.5 software to preprocess S2B_MSIL1C product for atmospheric correction. And thr results referred to L2A were successful. However, when I opened the results with 10 m or 20 m resolution in SANP, an error came up that the file couldn’t be open. I don’t know how I should do for solving it.

what version of SNAP are you using? The output format of sen2cor v2.5.5 has changed a little and to be able to open it you need SNAP v6.0.1: you have to install the version 6 and update it via: Tools->Plugin->Updates

Thank you. I have done it. And it works.
