Permission denied in windows 8.1

I am trying to compile the sketch but fedup

Tried :

  1. Full read write permissions to Temp folder
  2. set off UAC
  3. Cut the sketch to another sketch and re-compile
  4. set compatibility mode and done run as administrator
  5. right click and run as administrator
  6. deleted all temp files and re-started Arduino IDE
  7. Un-installed completely (Clear Registry, Delete all Folders etc...) and re-installed Arduino

but still this damn error remains ... please help.... I am frustrated ..

Error compiling for board Arduino/Genuino Uno.

This sort of error could be caused by your antivirus software. Try TEMPORARILY disabling your antivirus for a single compilation to see if the problem goes away, then turn the antivirus back on. If the problem doesn't occur with the antivirus off you will need to adjust the settings of your antivirus to whitelist the appropriate file, folder, or process so it doesn't interfere with compilation.
