Invalid library found

Hi Everyone,

Fairly new to all the arduino stuff and working on my first LED strip project ^-^ . I have encountered a problem after trying to load a zip file to the library. Now when I want to install one with " manage library's" it starts installing and then makes a folder named "arduino ******"(numbers) in library and says its invalid. After deleting the folder from both users arduino folder and c/programmfiles(x86)/arduino/librarys it keeps doeing the same. Have uninstalled arduino, removed every single trace I could find from arduino and installed again and it keeps doing this over and over....... anyone an idea of what i am doing wrong? I cant seem to find it anywhere.

Thanks :slight_smile:

It sounds the same as this:

which turned out to be caused by their antivirus software. Make sure nothing is preventing the Arduino IDE from writing to the {sketchbook folder}/libraries folder (you can find/set the location of the sketchbook folder at File > Preferences > Sketchbook location).

You could try TEMPORARILY disabling your antivirus software for only the time it takes to install the library to check if that's the cause. If so, you will need to figure out how to whitelist the Arduino IDE, process, or folder in your antivirus settings for a permanent solution to the problem since it's not a good idea to have to disable the antivirus every time you need to install a library.

Thanks! I read through it and it might be (99% shure :confused: ) Bit Defender als also stated in your link. I installed it last week. Gonna try it tomorrow :). Thank you so much in advance. I will let you know it it is solved

Edit :

Problem is solved! You are the best :wink:
