Explorer Windows 20.1 Beta 3 available. It can be found here: 


Here is what's new in this release:



- Added support for Single Sign On
- Added support for Basemap by reference
- Added support for Map Expiration
- Now showing sideloaded basemaps in basemap tool

Team worked pretty hard on this one please let us know what you think,

We are pushing out one last beta before our final release, and it's got some great stuff we want you to try out. Things like:


Support for on-demand offline map areas

A relatively new feature in ArcGIS is the ability to create offline areas based on web maps. It can be done two ways: map authors can predefine areas for mobile users to take offline, or mobile users can define the area they want to take with them 'on demand' whenever they like. We brought you the former in the last beta, and we bring you the latter in this beta. On-demand offline workflows provide great flexibility for your field workers. Feel free to try it out with your web maps! Be aware that taking maps offline on-demand packages up all your layers and basemaps in real time and can be somewhat resource intensive.



Support for adding and removing favorite maps

Does your organization have too many maps to keep track of? Would you prefer to have the handful you work with regularly pop to the top of your map browser in Explorer? Try out 'favorites', an easy way to keep track of maps you work with often. These favorites sync across ArcGIS, so maps marked as a favorite in Explorer will also show up as a favorite in ArcGIS Online or Enterprise (and vice versa).  



Switch to basemaps with different spatial reference systems

You asked for it, we're delivering it. If you have basemaps in your organization that have different spatial reference systems, you can now switch easily between all of them in Explorer. No longer are you stuck being able to only open basemaps that are in the same spatial reference system as your original map! 



In addition to those items, we've also been working hard to add:


  • Support for group layers in mobile map packages
  • Ability to refresh screen while browsing list of maps
  • Download on WiFi only setting
  • Feature search sorting enhancements
  • Definition query now honored when searching MMPK
  • Capability to search for a coordinate
  • Improved error messages when using custom URL schemes
  • Various bug fixes
  • Updated translations


You can find all of these updates in the Microsoft store by searching for 'Explorer for ArcGIS beta' (they will be available soon as a sideloadable package; I'll edit that into the blog here when it is ready). Dig in, try it out, and leave us feedback to let us know how it's going. We look forward to wrapping things up in the beta and getting the initial release of Explorer for ArcGIS on Windows out soon!


Happy Exploring!

Beta 3 is now available in the Microsoft Store! We've got lots of great updates for you, including:

  • The ability to side-load Explorer onto your Windows device. Can't use the Microsoft Store? Use the info in Justin's blog to download and install Explorer locally. 
  • Support for web maps that have pre-planned offline areas. Map authors can define areas within web maps that mobile users can download and use when offline. Windows 10 Explorer users can now download and use these areas on their devices.
  • Markup improvements such as adding notes to the markup objects, changing the color of markup items after they've been created, and toggling the fill shading for enclosed markup objects.
  • You can now copy text from a popup. 
  • Anonymous logins are now supported, so you do not have to have an ArcGIS account to use Explorer beta 3. This is really handy if you want to create public / anonymous mobile maps (requires the Publisher extension) and share them with people outside your organization.
  • The option to return to the default basemap for the current map.
  • The ability to specify the preferred coordinate notation. 
  • You can view map details from the Map card, including summary, date modified, and description.
  • There are now separate tools for viewing map layers and the map legend.
  • Updated localization.
  • Lots of bug fixes.


You can find all of these updates in the Microsoft store by searching for 'Explorer for ArcGIS beta' - or by downloading and installing Explorer locally using the instructions in the sideloading blog.


We're getting close to an official release later in the summer, so make sure you keep trying things out and letting us know what's working - and what's not working - so we can keep trying to get all those bugs squashed.


Happy Exploring!

Explorer for ArcGIS for Windows is built with Microsoft’s Universal Windows Platform (UWP). For information about UWP apps, see the following Microsoft documentation: What's a Universal Windows Platform (UWP) app?. Typically, you install UWP applications from the Microsoft Store.

However, if you can’t access the store, there is another option—sideloading. This allows you to install apps on Windows 10 devices without going through the Microsoft Store. Follow the steps below to install Explorer for ArcGIS via sideloading on your Windows 10 device.


Before you start, see which version of Windows 10 you have and make sure your device meets the minimum requirements. Explorer for ArcGIS for Windows requires Windows 10 version 1803 (OS Build 17134) or higher.


Enable Windows 10 for sideloading


By default, Windows 10 only allows you to install applications from the Microsoft Store.  To install from other sources, you need to enable sideloading:

  1. Open Settings.
  2. Click Update & Security > For developers.
  3. Under Use developer features, select Sideload apps.



Or for some PowerShell "fun":

  1. Run PowerShell with administrator privileges.
  2. Run this command:
    reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock" /t REG_DWORD /f /v "AllowAllTrustedApps" /d "1"


For more information on enabling sideloading see:

Enable your device for development – Sideload apps

Download and install Explorer for ArcGIS


To download and install Explorer for ArcGIS:

  1. Download Explorer for ArcGIS for Windows
  2. Extract the contents of the downloaded file.
  3. Launch the installer (Double click on .appxbundle file)
  4. Click the Install button.





If you get an “App installation failed with error message: Install failed.” error (or something similar) while installing with App Installer following the steps above, you can try to install Explorer for ArcGIS with the Add-AppxPackage cmdlet using PowerShell.


To install Explorer for ArcGIS from PowerShell:

  1. Run Windows PowerShell
  2. Change to the directory where you extracted the installer after download.
  3. Run this command (make sure to change the filename if installing a different version):
    Add-AppxPackage -Path .\Explorer_19.1.1.0_x86_x64.appxbundle


Beta 2 for Explorer for ArcGIS (WIndows) has just been released to the Microsoft Store! There are lots of good updates in beta 2, but before you rush out and download it we have a very important announcement:


Before installing beta 2, uninstall any previous versions of Explorer for ArcGIS on your Windows machine!


There have been some major under-the-hood changes that will cause Explorer to crash if you don't perform a fresh install for beta 2 (this release). Ok, with that taken care of - back to the good stuff!

    First of all thanks for showing interest in Explorer on the Windows platform. The team is really looking forward to working with you to build this next version of Explorer.


    Here are some quick steps to get you started:

    1. Fill out the survey here: Explorer for ArcGIS - Windows Early Adopter Program Survey 
    2. At the end of the survey, you will find a link to the Microsoft Store listing.
    3. Download the app to your Windows 10 device.
    4. Break things and let us know about it  Were serious about this part, don't let us get away with anything. Let us know when and where the app needs to improve. You can do this is a couple of ways:
      1. Put an issue in on the geonet site: ArcGIS Explorer Beta 
      2. Or ... you could put a bug in the #bugs channel in our public slack workspace note: the first time you will need to setup a free account here:


    Thanks and we're looking forward to working with you on this app.

    -The Explorer Team

    For this beta program, we will be using the Microsoft store to deploy the app. The first step is to ensure that you have a Microsoft account. If you don’t have one, you can get one

     here: The next step is to make sure that you are logged in to the Microsoft store on your device with this account. This process can be a little tricky, so we thought it might be a good idea to write up some tips that may help you get unstuck.


    The first step is to make sure you’re logged in as the right user. I know I’m sounding a little like Captain Obvious here, but the store allows you to be logged in as multiple users at once, which can lead to a bunch of confusion.


    It is key to make sure that the email you gave Esri is associated with the Microsoft account you are logged in to the Microsoft Store with. To avoid any confusion, we recommend signing out of any other accounts and just being logged in as the user you provided to us after completing the survey. This will ensure that you can actually see the listing for Explorer Windows and download the app.
