Can't install plugins!

Today I saw follwing error:

Warning - could not install some modules: S1TBX Feature Extraction Tools - The module named org.esa.snap.snap.raster was needed and not found. 2 further modules could not be installed due to the above problems.

do you have any idea what I can do about it?

This could either be caused by a temporary server issue or your local SNAP installation is corrupted.
Could you tell a bit more about your SNAP. Which version have you installed? Have you tried to update SNAP or was your intention to add the S1TBX to an existing SNAP installation?

It was 6.0.0 I believe. I deleted it, installed once again and it’s ok now, thank you

Please also install all the module updates that are available.
