Cannot Install Library

(This is an example using the Audio library by Arduino.)

Any time I attempt to install a library via Sketch -> Include Library -> Manage Library
I get an error that says:
"Invalid library found in C:\Users\Computer\Documents\Arduino\libraries\arduino_131210:"

There is a folder that is created called "arduino_131210" that contains no data or files.

I've updated my Java. Also tried to find out how to install the .zip library files manually, but don't really know where to find the .zip files at.

Any help would be appreciated!
Want to get some libraries installed, so I can start tinkering!

Hey Delta_G, thanks for the response!
You're right, I can install libraries manually, which is awesome. Thank you for that!

What about the libraries that are found when I go, inside of the Arduino IDE, Library Manager.
Those ones all give me an error that says "Invalid library found in C:/..."

Any suggestions on that one, or where I could find the manual install online?
Thanks!

It sounds like the same problem as this:

which was determined to be caused by the antivirus software.

Try TEMPORARILY disabling your antivirus just long enough to try installing the library again. If that works you will need to adjust your antivirus software's settings to whitelist the necessary file, process, or folder to allow you to install libraries in the future with the antivirus on.

You rock! That was the case. I have BitDefender as well. Added it to my whitelist and off we go!

Thanks so much for the help! Much appreciated!

I have BitDefender as well and am having the same problem. Could you please explain how I can add it to my whitelist and what to add? Any help would be much appreciated.

Hello,
I had the same problem with BitDefender. I cannot install new libraries to Arduino IDE and I didn't know why. I searched so much in Internet and I read these posts and came to my mind that antivirus can be the problem. To install libraries it is needed unblock Java Platform in one of options BitDefender ("Safe Files").

It can be helped and worth not lost time.
