Error while installing SDK Component

hello,

I'm trying to install SDK component for PDF export from below page, but each time I get the same error :"Failed to discover all connectors".

I've tried to solve this by applying solution from the following post, but I do not see where  in DS we've got : "Export - Option tab ,the bullet "Generate p2 repository" to be able thick or un thick something...

Also, closing/reopening of DS gives nothing, so it's quite annoying.

Error details : Failed to discover all connectors. RepositoryDiscoveryStrategy failed with an error Failed to process repository contents No repository found at jar:file:/C:/Users/xxxxxxxx/Desktop/DESIGN_STUDIO_install/FileSaver.js-master.zip!/.

(I work in local)

Kind Regards,

Beata
