    Hi Don Weavers,

    In addition to the AI Answer’s suggestions, I recommend checking the Dexcom Uploader itself, as it may be installed but not running correctly or may not be detected by Dexcom Clarity.

    First, check the notification area near the clock for the Dexcom Uploader icon. You can also press Ctrl + Shift + Esc to open Task Manager. If Dexcom Uploader is listed, select it, choose End task and then reopen it from the Start menu.

    If the issue continues, uninstall Dexcom Uploader from Control Panel > Programs > Programs and Features, restart the computer and reinstall the latest version directly from the official Dexcom Clarity website. Dexcom states that the uploader must be installed and running for it to work.

    I also recommend checking Windows Security > Virus & threat protection > Protection history to see whether the official Dexcom installer or uploader has been blocked. Only restore or allow an item after confirming that it belongs to the official Dexcom software.

    You can also test the uploader from a new Windows user profile to determine whether the issue is limited to the current profile:

    1. Open Settings > Accounts > Family & other users.
    2. Select Add someone else to this PC.
    3. Select I don’t have this person’s sign-in information > Add a user without a Microsoft account and complete the setup.
    4. Sign in to the new account and test the latest official Dexcom Uploader.

    This is only a diagnostic test and will not remove the existing profile or its files. If Dexcom works in the new profile, the issue is likely associated with the original profile or its app settings. If it fails in both profiles, the problem is more likely related to the Dexcom installation, security permissions or Windows. Please do not move your files or delete the original profile at this stage.

    Since this is medical-device software, I would avoid registry changes, unofficial installers or downloads from third-party websites. If the latest official uploader still cannot be detected, please contact Dexcom Technical Support for product-specific assistance with the uploader and receiver.

    Please also note that Windows 10 reached end of support on October 14, 2025. If the PC is eligible, I recommend moving to Windows 11 for continued support and security updates.

    I hope these additional checks help identify what is preventing the uploader from being detected. Please keep me updated on how it goes.

    Try these steps in order:

    1. Restart Windows first
      Go to Start > Power > Restart. If Windows was recently updated, a restart can restore app installation and launch behavior.
    2. Reset Microsoft Store
      • Press Windows key + R
      • Type wsreset.exe
      • Select OK
      • Wait for the blank Command Prompt window to close and for Microsoft Store to reopen automatically
      • Search for Dexcom again in Store
    3. Repair or reset the Dexcom app
      • Go to Start > Settings > Apps > Installed apps
      • Select the Dexcom app
      • Select Advanced options
      • Choose Repair first
      • If it still fails, choose Reset
      Note: Reset may remove the app’s local app data.
    4. If Dexcom is not under Installed apps, check System components
      Some apps may appear under Settings > System > System components. If Dexcom appears there, open its Advanced options and use Repair or Reset.
    5. Check whether security software is blocking the app or its uploader component
      On Windows 10, some modern apps can be blocked by security software. If Dexcom or its uploader is being blocked, add the affected app to the allow list in the security software.
    6. If Store still says it cannot find or install the app, check these conditions
      • The app may no longer be available in the current country or region
      • Family settings may be hiding it
      • The app may be incompatible with the device
      • The PC may not be authorized for Microsoft Store apps; sign in to Store with the Microsoft account used for the app
    7. If the app is installed but cannot be found to open it
      • Select Search on the taskbar and type Dexcom
      • Or press the Windows key and start typing Dexcom
      • Also check Start > All apps

    If the problem is specifically that Dexcom reports it cannot find its uploader, that usually points to either a broken app install, blocked app component, or a Store app state issue. The most relevant path is: Restart > wsreset.exe > Repair > Reset > check security software allow list.
