Can't set an active Library

[Rovitracker]

I have all my footprints needed for this board in one folder. I decided to make a few changes to the existing board which I was able to get fabricated.

So I have to add 2 new footprints to the existing folder. I did that but then for some reason, That library disappeared. I’m trying to add that library again using under the “preferences tab”. But for some reason under “status”, it says “INVALID” and the folder is not added to the library.

How do I fix this problem?

I have attached a screenshot of the problem. Please help!

Firstly, welcome to the forum.
You don’t say what version of KiCad that you are using but the libraries you are looking at are from KiCad 4 (they are named as plurals - the version 5 libraries are singular) I would suggest that you have a look at the FAQs, particularly. If you are using 4, I would strongly recommend updating - most users are now using 5, it has many bugfixes.

And if you are now using KiCad 5 but previously were using 4, this may be of help

I had KiCad 4 installed previosly. Now i updated to v5. Now i have some problems with the library setup

Recommended reading: https://forum.kicad.info/t/library-management-in-kicad-version-5/14636 KiCad does not automatically discover libs. Nor does it update the list of libraries on update. If you had KiCad 4.0.x installed previously then i would bet you still have parts of its configuration surviving. Most importantly the fp-lib-table. This file controls which footprint libs you use. If this is the case then you probably still run the on demand online footprint libs originally “distributed” wit…

I uninstalled Kicad 4 and installed 5. I got the following error.

Nevermind … Fixed it finally. Thank you
