Problem to open sfdumanifest.xml file with SNAP


I tried many times with 4 images OLCI _Level 1 and OLCI Level 2 to open the file : xfdumanifest.xml in SNAP.
I also redownloaded SNAP with last updated. I checked : Plugins and S3TBX. I have all files needed.
This the message :SNAP error
No appropriate product reader found. File … can not be opened.

I read some other posts having the same problem.
What is the solution ?

I can read the .nc files but without the xml file I can`t process (ex. reprojection )
Thank you for help


I solved my problem by redownloading the data again and it works.
