When i run processing video library it tells me not installed properly

i download it from the contribution manager in processing. it still has error

close processing after download library then open it again

or try to call the library from the sketch

i am using win7 64 its working with me

i try restart processing .it doesnt work and i use win 10 ,by the way ,what do you mean call the library from the sketch

i mean from the sketch make import library

other thing check name and path of the library where its installed and downloaded

the last thing you can try delete the library and reinstall it again
