If you receive the following Windows error message:

Windows can't find 'C:\Program Files\Autodesk\AutoCAD 2023\AdReset.exe'. Check the spelling and try again.

it indicates that Windows is attempting to launch a program that no longer exists at the specified location. This problem commonly appears after uninstalling Autodesk AutoCAD, moving program files, antivirus quarantine, incomplete software updates, or leftover startup entries.

Although the message specifically mentions AdReset.exe, the troubleshooting methods discussed in this guide apply to any missing executable file referenced by Windows.

This article explains why the error occurs, how to identify the source, and how to permanently resolve it.

What is AdReset.exe?

AdReset.exe is an Autodesk utility included with certain versions of AutoCAD. Depending on the release, it may be used to:

• Reset AutoCAD settings
• Restore user profiles
• Reset configuration files
• Perform maintenance tasks during startup

If the executable is removed but Windows still attempts to execute it, the "Windows can't find" error appears.

Why Does This Error Occur?

The error itself does not necessarily indicate corruption in Windows.

Instead, it usually means that some Windows component is still trying to launch a file that no longer exists.

Common causes include:

• Incomplete AutoCAD uninstall
• Manual deletion of AutoCAD folders
• Antivirus quarantine
• Startup shortcut pointing to deleted file
• Scheduled task referencing old executable
• Registry startup entry
• Explorer shell extension
• Third-party optimization software
• Broken desktop shortcut
• Incomplete Autodesk update

Common Symptoms

You may notice:

• Error appears during Windows startup
• Error appears after login
• Error when opening File Explorer
• Error while launching AutoCAD
• Random popups every few minutes
• Slow Windows startup
• Multiple missing executable errors

Step 1 – Verify Whether AutoCAD Is Still Installed

Open:

C:\Program Files\Autodesk\

Locate:

AutoCAD 2023

Check whether

AdReset.exe

exists.

If the file exists

Possible issues include:

• Corruption
• Antivirus quarantine
• Incorrect permissions

If the file is missing

Windows is referencing a file that no longer exists.

Step 2 – Check Startup Folder

Press

Win + R

Run

shell:startup

Delete any shortcuts pointing to:

• Autodesk
• AutoCAD
• AdReset.exe

Next check:

shell:common startup

Remove obsolete shortcuts.

Step 3 – Check Startup Apps

Open

Task Manager

Navigate to

Startup Apps

Disable any Autodesk-related startup entries.

Step 4 – Check Scheduled Tasks

Open

taskschd.msc

Browse

Task Scheduler Library

Look for tasks named:

• Autodesk
• AutoCAD
• AdReset
• AutoUpdater

Delete or disable tasks pointing to missing files.

Step 5 – Check Registry Startup Entries

Open Registry Editor

regedit

Check:

HKEY_CURRENT_USER
Software
Microsoft
Windows
CurrentVersion
Run

and

HKEY_LOCAL_MACHINE
Software
Microsoft
Windows
CurrentVersion
Run

Remove values referencing

AdReset.exe

Step 6 – Search Entire Registry

Inside Registry Editor:

Press

Ctrl + F

Search:

AdReset.exe

Delete obsolete entries.

Press

F3

to continue searching until no matches remain.

Important: Always back up the registry before making changes.

Step 7 – Check Windows Services

Open

services.msc

Look for Autodesk-related services.

If any service points to a missing executable:

• Disable it
• Remove it after confirming it is obsolete

Step 8 – Check File Explorer Context Menu

Sometimes Explorer extensions attempt to load missing files.

Use Microsoft's Autoruns utility to inspect:

• Explorer Shell Extensions
• Context Menu Handlers
• Explorer Add-ons

Disable broken entries.

Step 9 – Check Desktop and Taskbar Shortcuts

Delete shortcuts referencing

AdReset.exe

Recreate them if AutoCAD is still installed.

Step 10 – Search Entire Computer

Open Command Prompt

Run

dir C:\*AdReset* /s /b

or

where /r C:\ AdReset.exe

This confirms whether the executable exists elsewhere.

Step 11 – Repair AutoCAD

If AutoCAD is installed:

Open

Settings

Go to

Installed Apps

Select

AutoCAD 2023

Choose

Modify

Then

Repair

If repair fails, reinstall AutoCAD.

Step 12 – Check Antivirus Quarantine

Some antivirus products may quarantine executable files.

Check your antivirus quarantine.

Restore the file if it was falsely detected.

Step 13 – Use Microsoft Autoruns

Microsoft Sysinternals Autoruns is the most effective tool for diagnosing missing executable references.

It scans:

• Startup folders
• Registry Run entries
• Scheduled Tasks
• Services
• Explorer Extensions
• Browser Helpers
• Drivers
• Shell Extensions
• Logon Scripts

Search:

AdReset.exe

Disable or delete broken references.

Advanced Troubleshooting

Use Process Monitor (ProcMon) to identify which process attempts to launch the missing executable.

Filter:

Path contains AdReset.exe

The captured process reveals the source immediately.

Event Viewer Investigation

Open

eventvwr.msc

Review:

• Application Logs
• System Logs

Look for:

• Application Errors
• Startup Failures
• Explorer Errors

Command Line Checks

Search registry:

reg query HKCU\Software\Microsoft\Windows\CurrentVersion\Run

Search machine startup:

reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run

Check scheduled tasks:

schtasks /query /fo LIST /v

Prevention Tips

To avoid similar issues:

• Always uninstall AutoCAD using the official uninstaller.
• Avoid manually deleting program folders.
• Keep Autodesk software updated.
• Regularly review startup entries.
• Periodically inspect scheduled tasks.
• Use trusted antivirus software.
• Create restore points before major software changes.

When Should You Reinstall AutoCAD?

Reinstall AutoCAD if:

• Multiple Autodesk files are missing.
• AutoCAD crashes frequently.
• Repair installation fails.
• Registry references are severely damaged.
• Required components have been deleted.

Conclusion

The "Windows can't find AdReset.exe" error is usually caused by leftover Windows references pointing to a deleted Autodesk executable rather than a Windows malfunction. By systematically checking startup entries, scheduled tasks, registry keys, services, Explorer extensions, and using tools such as Microsoft Autoruns, you can quickly locate and remove the broken reference. If AutoCAD is still installed, repairing or reinstalling the application is often the fastest and most reliable solution.

Frequently Asked Questions (FAQ)

1. What is AdReset.exe?

It is an Autodesk utility associated with certain AutoCAD installations that helps reset application settings and configuration.

2. Is AdReset.exe a virus?

No. The genuine file is a legitimate Autodesk component. However, malware may occasionally use similar filenames, so verify the file's location and digital signature.

3. Why does Windows keep looking for AdReset.exe?

A startup item, scheduled task, registry entry, service, or shortcut still references the missing file.

4. Can I simply copy AdReset.exe from another computer?

No. Reinstall or repair AutoCAD instead, as copying a single executable may not restore all required components.

5. How do I know what is launching AdReset.exe?

Use Microsoft Autoruns or Process Monitor to identify the exact startup component.

6. Will deleting registry entries fix the issue?

Yes, if the registry entry is the source of the broken reference. Always back up the registry first.

7. Is reinstalling Windows necessary?

No. In most cases, removing the invalid startup reference or repairing AutoCAD resolves the issue.

8. Can antivirus software cause this error?

Yes. If the antivirus quarantines AdReset.exe while leaving startup entries intact, Windows will display this error.

9. Does this issue affect system performance?

It can slightly increase startup time and generate recurring error dialogs, but it generally does not damage Windows.

10. What is the quickest way to find the broken reference?

Use Microsoft's Autoruns utility, search for AdReset.exe, and remove or disable the invalid entry.
