I had used Arduino UNO about 3 years ago and it was working fine. I could not work on it as I got busy. I wanted to restart my projects and I downloaded the latest IDE 1.8.5. Even the blink sketch example would not compile. I tried many times. It would compile a few times and loads on the arduino. I wanted to start with a clean IDE so I deleted all the old software and downloaded the new IDE 1.8.5. Now it does not compile at all.
My software is located on a Dell Vostro laptop using OS: WINDOWS 7. I am using Arduino UNO and Port: COM4 on USB.
Attached file gives the result of compilation error.
Any help in fixing the problem will be greatly appreciated.
