MKR1000 error compiling

When I try to upload my code to Arduino MKR 1000 it shows this error message:

Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino MKR1000"

C:\Users\UÄŤenik\Documents\Arduino\sketch_feb13b\sketch_feb13b.ino:7:21: fatal error: WiFi101.h: No such file or directory

compilation terminated.

exit status 1
Error compiling for board Arduino/Genuino MKR1000.

Please help!

Don’t post screenshots of text! That is very unhelpful. What’s worse is your screenshot only shows the very last fragment of the error, which is all but useless. When you encounter an error you’ll see a button on the right side of the orange bar “Copy error messages”. Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar). It is almost never appropriate to post screenshots but in some cases it is helpful to post images. You should attach and embed the image following these instructions:

Have you installed the required packages for the MKR1000 ?

Type "MKR" into the search box and press ENTER
Select "WiFi101" from the list
Wait until it has completed.
RESTART the IDE (optional but sometimes worth it).

Problem solved! It was another library that was causing the problem. Thanks anyways!
