WinRAR: Access is Denied when archiving

When you open WinRar make sure you right click and select "Run As Administrator". even though you are a administrator user programs you run will not have administrator privileges unless you do that.

If the files are still not readable that means either the file is in use and has a exclusive lock, or that the administrator does not have permissions to read. One thing I would recommend is use Total Commander to copy the file before you try coying it. I have used it to copy files that are being difficult. It will elevate itself to administrator privileges if it needs to.

Right-click on the archive, Properties then, in the attributes deselect "read-only".
