Can't install El Capitan b/c of Filevault Encryption?

El Capitan is downloaded and ready to install but when I click on the hard drive it won't let me--saying my FileVault is getting encrypted. I went "system preferences" then "security & privacy" and put in security password. I clicked on "turn off FileVault" but it won't let me saying the encryption needs to be done first. The estimating time remaining is "21 hours remaining" but goes up or down by a minute, never really going down.

MacBook Pro (15-inch Mid 2012), iOS 9.0.2

Have you figured out how to resolve your issue with the "The Core Storage operation is not allowed on a sparse logical volume group. Quit the installer to restart your computer and try again" error message?

I am stuck at the exact same point

Thanks Allen,

It was the only way I could stop FileVault and do a clean install of El Capitan from a bootable disk.

Thank you Allen! This helped. I had the same problem on El Capitan and wanted to upgrade to Sierra.
