2.8 addon Fast carve

having problem to re open file for 2.8 with error on addon !

looks like this Fast carve addon has been installed in a 2.8 file

how do I de install it

thanks
happy bl

UPDATE your version of 2.8
then if it still errors
go to>>>
C:\Users\YOURNAME\AppData\Roaming\Blender Foundation\Blender\2.80\Scripts\addons\fast-carve-fast-carve-2-8
and remove folder >>> fast-carve-fast-carve-2-8

looks like this file is totally loss cannot even append things
so will have to redo another new file from scratch !
if I cannot redo error then file is useless for bug report I guess

thanks anyway
