Unable to upload Arduino software

Trying to upload software from Arduino and will not go threw clean. I had to hit Ignore Three times.
After doing this I tried to compile the blink sketch and said the file does not exist.

Can't write: C:\Program Files (x86)\Arduino\hardware\tools\avr\avr\bin\ar.exe

This is as far as got on the first Failure.

I am a Newbie. I try the simple thing and it work. Restarted my Computer. Thank you for your help
