The install version is probably fine. Take a look at the date of the install. Go into your Date and Time, unlock it, turn off the auto Apple update, turn the date back to a few months after the date on your install and do the installation.

If you are trying to do an internet install the date trick will not work. You are going to have to have a download install on an external boot drive. Or you can do this in Target Mode with another Mac running El Capitain.
