Sen2cor issue in SNAP


I have followed this tutorial when converting Sentinel-2 L1C to L2A Sen2cor (detailled instructions) but the issue still remain as follows:
L1C user product directory must match the following mask: S2?_MSIL1C.SAFE*
but is: MTD_MSIL1C.xml
Finished tool execution in 1 seconds
The folder name:

and the documents within the folder:

There was no working at all when inputting ‘MTD_MSIL1C.xml’ through Sen2cor I/O Parameters.
I also put .SAFE file in C drive for less subfolders of path, which was not working.
Really don’t know what I can do further to make it work. Any suggestions will be appreciated!

Probelm was solved via Sen2Cor-02.05.05-win64 - AttributeError: 'L2A_Tables' Object has no attribute '_L2A_Tile_PVI_File' - #4 by Fabrizio_Ramoino

So I still cannot figure out processing it with sen2cor in SNAP GUI but it worked with command line. Also trying to reduce the number of subfolders in the path where the .SAFE is stored.
