What are ProximityUxHost.exe Error Messages?

ProximityUxHost.exe Runtime Errors

Runtime errors are Windows errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when ProximityUxHost.exe is attempted to be loaded either when Windows is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Windows.

In most cases, ProximityUxHost.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these ProximityUxHost.exe error messages mean that Windows was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Windows will be unable to start without resolving these errors.

Some of the most common ProximityUxHost.exe errors include:

ProximityUxHost.exe - Bad Image.
ProximityUxHost.exe Application Error.
ProximityUxHost.exe could not be found.
ProximityUxHost.exe could not be installed.
ProximityUxHost.exe could not be launched. Class not registered.
ProximityUxHost.exe could not be started.

Error starting program: ProximityUxHost.exe.
Faulting Application Path: ProximityUxHost.exe.

System Error

The program can’t start because ProximityUxHost.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the ProximityUxHost.exe error is key to properly resolving these errors. Although most of these EXE errors affecting ProximityUxHost.exe will happen during startup, occasionally you will encounter a runtime error while using Microsoft® Windows® Operating System. This can occur due to poor programming on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of ProximityUxHost.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix ProximityUxHost.exe Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your ProximityUxHost.exe issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the ProximityUxHost.exe error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing ProximityUxHost.exe file.

System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt ProximityUxHost.exe files (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "cmd" but DO NOT PRESS "ENTER".
Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
You'll be prompted with a permission dialog box.
In the box, click "YES".
You should have a black screen with a blinking cursor.
In that black screen, type "sfc /scannow" and hit "ENTER".
SFC will begin scanning for ProximityUxHost.exe issues and any other system file problems.
Follow any on-screen commands to complete the process.

Please be aware that this scan might take a while, so please be patient while it is working.

If this Step 2 fails as well, please proceed to the Step 3 below.

sfc /scannow

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many ProximityUxHost.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the ProximityUxHost.exe error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

Download ProximityUxHost.exe Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying ProximityUxHost.exe to your appropriate Windows system directory. Microsoft typically does not release Windows EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing ProximityUxHost.exe and all other EXE files for Windows. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
