Could not find boards.txt error


Sometime ago I reinstalled Arduino but I put it in C:\Program Files (x86)\Arduino. I had to move the sketch folder back to ...\Documents for some software to run correctly. So now I have the sketch folder in ...\Documents\Arduino\sketches. The library folder I have been using however is in C:\Program Files (x86)\Arduino\libraries.

I get this error in the IDE debugger window when using the boards manager:

"Could not find boards.txt in C:\Users\Perigalacticon\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.6.10. Is it pre-1.5?"

Do you know how I can resolve this? I'd like to have everything installed and running correctly.

That's just a warning, not an error. Delete the folder C:\Users\Perigalacticon\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.6.10 and it will go away.
