i have install plugin too but i give an error that "error uploading , if the selected board is currently avilable"
Did you say YES to the CERTIFICATE during install ?
Without that you will not be able to connect.
Same with any additional drivers, firewall permissions etc.
What colour is the CREATE icon in the taskbar ? (working should be teal / arduino blue)
Are you just a "user" of that computer or did you install as "administrator" which is the best option.
What is your internet connection as some ISP's may also cause minor issues.
Hi @mittalv,
which board did you selected in the boards dropdown? it's recognized as 'connected'?
