Which app or program to open grib files from Winmor

[Goudurix]

Hi,

am running Winmor-Winlink on HF.
I can request grib files and do receive them.
I installed ZyGrib and could open them there but they don't open on a map.
I hten removed all the ZyGrib files (uninstall not possible) and since then the grib file attachments from winlink open in Wordpad hence unreadable.

So I need to find a grib file reader that overlays the winlink-received grib files onto the right zone in a map.

Help!
