Summa registration marks

[Heidi5EBE]

Hi, Ive used summa cc2018 in illustrator 2020, but now that ive updated to illustrator 2021, it disappeared. Anyone who knows how to install it again?

I think the plugin must have a installation routine. Take a look into the manual or contact the vendor of the plugin.

check also idf there's a new version of the plugin that is compatible with the new Illustrator version.

This might not work, but you could try moving it from the 2020 plug-in folder to the 2021 plug-in folder.
