Conversion of Sentinel 2 L1C data to L2A

Actually, L2A data for my area of interest is not available on the portal for the whole year. How can I convert L1C products into L2A Products? I have downloaded SNAP 7 software. Can I do it using this software? IF yes kindly share the tutorials with me, please. I will appreciate a detailed answer as i am new to SNAP software.Thanks

You install sen2cor from the plugins menu and apply it to your L1C data to get L2A

I have tried to instal sen2cor 2.8 in SNAP 7 but failed…please tell me the correct method?

have a look at these instructions: Sen2cor 2.4.0 on SNAP 6.0
They were written for SNAP 6.0 and sen2cor 2.4.0 but are the same for SNAP 7.0 and sen2cor 2.5.5.
