Program1_Rev1.ino:5:20: fatal error: iostream: No such file or directory

compilation terminated.

I just registered because of the problem above, before the update my code had no problem, now i’m getting this, constantly, any clue how i can bypass this problem ? (I’m a enthusiast, doesn’t have any significant background in programming languages)

note1: I had some issues when the new installer required some java files, maybe it’s the cause ?

Thanks in advance,

The problem would seem to be related to the location of your directories.

I can understand that, but i have no clue on how i can fix it... hate when updating bring problems...
