Microsoft Store Installation and Update Problems

Use this page if you cannot find, install or update OMN4 in Microsoft Store, or the Store shows a blank window, Retry or Something went wrong.

Work through the relevant steps below, trying the download again after each one. Stop when it works. Keep any existing OMN installation while you resolve the problem.

If OMN4 has installed but its own window is blank or its menus turn black, use Blank Screens or Black Menus on Windows.

Find The Correct App

  1. On your Windows computer, open the OMN4 download page.
  2. Choose Microsoft Store under Windows. This takes you to the correct listing without needing to search.
  3. If your browser asks to open Microsoft Store, allow it. Check that the listing is Outdoor Map Navigator 4 by Anquet Technology Ltd.
  4. Choose Get or Install, then Open when installation finishes.

The direct link to OMN4's Store listing goes to the same app. Public Windows installation and updates use Microsoft Store.

OMN4 is separate from OMN2 and OMN3. An old desktop shortcut will still open the old app. Open OMN4 from its Store listing first, then find Outdoor Map Navigator 4 in Start. Right-click that entry to pin it to Start or the taskbar if you wish.

If An Update Is Missing

  1. Close OMN4.
  2. Click Start, type Microsoft Store and open the matching result.
  3. Open Library, then choose Get updates. Some Store versions show updates under Downloads or Downloads and updates instead.
  4. Let the updates finish. If OMN4 has an Update button, choose it.
  5. Open OMN4 again. Check Settings > About to see the installed version.

Microsoft Store normally updates apps automatically, though updates can be paused or managed by your organisation. If a particular new version is not offered yet, contact Anquet support with the version you have; uninstalling OMN4 is unnecessary for this check.

If you installed an older Windows download, version 4.0.2711 or earlier, follow Replace an Older Windows Download. Installing the Store app creates a separate copy, so follow that guide's data checks before removing the old one.

If Installation Stops Or Says Something Went Wrong

1. Check Windows And Restart

OMN4 requires Windows 10 22H2 or Windows 11. To check your version, press Windows + R, type winver and press Enter.

  1. Save your work and open Start > Settings.
  2. On Windows 11, choose Windows Update. On Windows 10, choose Update & Security > Windows Update.
  3. Choose Check for updates and install available updates.
  4. Choose Start > Power > Restart, then try installing OMN4 again from the download page.

If Windows Update itself fails, or settings are managed by your organisation, make a note of the message. A work or school computer may need help from its IT administrator.

2. Clear The Store Cache

This clears temporary Microsoft Store data. It does not uninstall OMN4 or delete your maps.

  1. Close Microsoft Store.
  2. Hold down the Windows key and press R, then release both keys.
  3. Type wsreset.exe into the Run box and press Enter.
  4. A blank command window should appear briefly, then close as Microsoft Store opens. Let it finish.
  5. Return to OMN4's Store listing and try Install or Update again.

A customer who could not install OMN4 confirmed that this resolved the failure on their laptop. It will not resolve every Store problem; if you see an error, keep its wording for support.

See Microsoft's Store cache instructions.

3. Repair Microsoft Store

  1. Open Start > Settings.
  2. On Windows 11, open Apps > Installed apps. On Windows 10, open Apps > Apps & features.
  3. Find Microsoft Store, open its menu and choose Advanced options, if available. On some Windows 11 versions it appears under System > System components instead.
  4. Choose Repair, let it finish, then reopen Microsoft Store and retry OMN4.
  5. If Repair does not help, return to the same page and choose Reset for Microsoft Store. You may need to sign into the Store again afterwards.

Check that you have selected Microsoft Store before using Reset. Resetting OMN4 itself can remove local app data and downloaded maps.

If Microsoft Store or Advanced options is absent, continue to the next section. See Microsoft's repair instructions.

If The Store Is Missing Or Remains Blank

One customer resolved an OMN4 installation failure by re-registering Microsoft Store for their Windows account after the usual checks had failed. This is a different repair from clearing its cache.

The checks below follow Microsoft's Store registration guide. If you would prefer help with commands, show that guide to Microsoft Support or your computer technician.

  1. Sign into the Windows account where the Store fails. Click Start, type Windows PowerShell and open the matching result normally.

  2. Paste this line and press Enter:

    Get-AppxPackage *Microsoft.WindowsStore*

  3. If package details appear, the Store is already registered for this account. If the earlier repairs have failed, contact Microsoft Support with those results.

  4. If nothing appears, ask your administrator or technician to check that the package exists using Get-AppxPackage *Microsoft.WindowsStore* -AllUsers in an administrator PowerShell window. If no package is found, contact Microsoft Support.

  5. Once the package is confirmed to exist, return to a normal PowerShell window under your usual Windows account. Paste this line and press Enter:

    Add-AppxPackage -RegisterByFamilyName -MainPackage Microsoft.WindowsStore_8wekyb3d8bbwe

  6. If it reports an error, stop and keep the wording for support. Otherwise, close PowerShell, open Microsoft Store from Start and retry OMN4.

The registration command must run under the affected account; running it as a different administrator can register the Store for the wrong person.

If It Still Does Not Work

Check whether existing apps in the Store's Library can update. You do not need to buy or install another app for this check.

  • If other apps fail too, or the Store itself stays blank, contact Microsoft Support or your computer technician. Explain what failed and which repairs you have tried.
  • If only OMN4 fails, contact Anquet support. A successful update to another app is useful information, although it does not rule out a Store problem.

Include the exact error code, if one appears, a screenshot or photo of the whole Store window, your Windows version, whether other apps update, and the steps already tried. If updating OMN4, include its version from Settings > About if you can open it.

App Will Not Start

Recover safely when OMN4 will not open.

Blank Screens or Black Menus on Windows

Update your graphics driver or try software rendering when OMN4 does not draw its windows correctly.
