I have recently downloaded ArcGIS_Desktop_104_149411 and  ArcGISPro_5023_149395  Trial versions. After I install them, both apps state that I need an update " A service pack is required on this Operating system. See http://support.esri.com for more information " When I go to the site there are all kinds of updates so I download the one for Desktop and try to install and it says "  The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch. " What do I need to do?

you installed and registered it before doing any patching I hope.  If this is for Arcmap version 10.4, the only thing there applies to an internationalization of languages.  check it out.  Upgrading the patch isn't required, but I don't think you have completed and registered the installation.  In any event, the site is here

What version of Windows do you have? Also mention the service pack, if any.

EDIT: Did the above mentioned products got installed, or just extracted followed by the error message?

Make sure you meet the minimum requreiments for both softwares too

As Dan mentioned, it might help to make sure they are registered before applying any patches.  typically Pro is done/upgraded after you successfully log in to your ArcGIS Online account that is assigning the Pro license (With the Pro software).

arcGiS  should allow you to register before needing to apply patches for the ArcGIS Desktop software...that is why it sounds more like it is missing a systew requirement.

Do you have other ArcGIS software installed on that machine?  You need to uninstall previous versions first.

Also, you mention it is a trial license....is that thru you customer number, or from a book or class?  each may have a different process to correct any issues.

Rebecca has a point, academic licenses are often (but not always) renewed at the beginning of May which requires a new license, so if this is through a university/college, contact the person responsible for licensing.

This message implies that the Operating System you're installing on needs a Service Pack to proceed with the ArcGIS for Desktop installation. For instance, the minimum requirement for Win 7 is Win 7 SP1.

Compare your Operating System and SP level with the product system requirements:
