arduino.ar reason: File exists

I already tried running as administrator, in Arduino IDE 1.8.4 and 1.8.5 installer and portable #2987

@sabas1080 I suggest a clean install. That includes deleting the Arduino15 folder. Don't forget to back up your projects before deleting.
Closing as can't reproduce.

Also try cleaning and deleting Arduino15 and the same error

I believe this problem is caused by not closing your file before exiting Arduino. The first time this happens running as administrator may work. The second time, it will be the administrator's working file and Windows will protect it. It is not the only file involved.
So find the file's Temp directory by doing a search on the file and delete the Temp directory. This worked for me and so far so good.
