To work correctly with Adobe Reader on the website of the AEAT it is necessary to have an updated version, depending on the version of the operating system.You can confirm which version you have installed by accessing the "Help" menu, "About Adobe Reader".

The configuration of Adobe may affect the documents provided by the AEAT in PDF through its website not being displayed or downloaded properly.For versions of Adobe 7 or higher, go to "Edit", "Preferences", "Internet" and uncheck the boxes "Show in reading mode by default" and "Allow quick view on web".

In addition, if any error persists related to the display of PDF documents you can try using the option "Repair installation of Adobe Reader" under the "Help" menu.

If you have difficulties printing the document PDF, it is recommended that the drop-down menu in the toolbar is set to 100% display.
