.gha Files already exists in your components folder and cannot be deleted while grasshopper is open. close grasshopper,

when I drag LB installer into grasshopper when I make the first toggle true it is ok. but the second one got an error with this title in stage 13:
.gha Files already exists in your components folder and cannot be deleted while grasshopper is open.
close grasshopper, delete the .gha files at:
C:\users\Accer\AppData\roaming\ grasshopper\libraries\ladybug_grasshopper_dotnet
and return this installer component
or simply keep using the old .gha component if you do not need the latest .gha component features.
I do as it says but it wont solve the problem.
I just started to import weather data but the tools look red and I got this message:
“No module named ladybug_rhino.grasshopper” when I run LB EPW map
and I got “No module named ladybug.futfil” when I run Download weather.
