Problem installing Acrobat Reader DC on El Capitan

Hi,

I'm using an iMac 20" with OSX 10.11.6 "El Capitan". I enter the Adobe download site and follow all the steps to download the Reader version for my OSX:

1.- Select Mac OS Intel 10.11

2.- Select the language (Spanish in my case)

3.- Select Reader 2019.010.20099 for Mac Intel, that is the only version available for the download.

The download goes well and I get the file in a few seconds. The problem starts when I try to install it because the installation goes well until the progress bar is in 58-60%, the process stops with a green tick and a full progress bar. I press Run Adobe Acrobat and the Adobe website opens showing an error message, the installation was incomplete and I have to try again.

I have downloaded the English version and averything goes perfect.

Could anybody tell me if there is any solution?

Thank you
