AutoCAD installation failures are usually caused by corrupted Autodesk services, damaged Microsoft dependencies, permission problems, insufficient disk space, or leftover components from previous installations.

If AutoCAD fails to install, stops near completion, rolls back unexpectedly, or displays errors such as 1603, 1618, 1722, 2738, 3001, or 4000, follow the procedures below in order.

Quick Diagnostic Table

Step 1: Perform Basic System Checks

Before modifying Autodesk components, eliminate the most common causes.

Run the Installer as Administrator

Procedure

1. Locate Setup.exe
2. Right-click the file
3. Select Run as administrator

Avoid launching the installer from a standard user session.

Disable Security Software Temporarily

Temporarily disable:

• Antivirus software
• Endpoint Detection and Response (EDR) software
• Third-party firewalls
• Windows Defender real-time protection

These products sometimes block:

• AdskLicensing
• ODIS
• Autodesk Access
• Installation scripts

Clear Temporary Files

Procedure

1. Press Win + R
2. Type:

%temp%

1. Press Enter
2. Delete all files and folders that Windows allows you to remove

Skip files currently in use.

Install Pending Windows Updates

Procedure

1. Open Settings
2. Open Windows Update
3. Install all pending updates
4. Restart Windows

Step 2: Verify Available Disk Space

Many users install AutoCAD on a secondary drive such as D:\ and assume the system drive is irrelevant.

It is not.

Even when AutoCAD is installed elsewhere, Autodesk installers extract large temporary packages on C:.

A lack of free space frequently triggers Error 1603 and rollback failures.

Recommended Free Space

Maintain at least:

• 30 GB free on C:
• Preferably 40 GB or more

before running the installer.

Step 3: Check Windows Installer Service

AutoCAD relies heavily on the Windows Installer engine.

Verify the Service

Procedure

1. Press Win + R
2. Type:

services.msc

1. Locate:

Windows Installer

Verify that the service is present and functioning normally.

Re-register Windows Installer

Procedure

1. Open Command Prompt as Administrator
2. Run:

msiexec /unregister

1. Run:

msiexec /regserver

1. Restart Windows

Step 4: Repair Windows System Files

Damaged Windows components often prevent Autodesk packages from installing correctly.

Run DISM

Procedure

1. Open Command Prompt as Administrator
2. Run:

DISM /Online /Cleanup-Image /RestoreHealth

1. Wait for completion

Run SFC

Procedure

1. Run:

sfc /scannow

1. Allow Windows to repair detected issues
2. Restart the computer

Step 5: Repair Autodesk ODIS Components

Modern Autodesk products depend on Autodesk On-Demand Install Service (ODIS).

A corrupted ODIS installation can stop AutoCAD before the actual installation begins.

Remove Existing ODIS

Procedure

1. Navigate to:

C:\Program Files\Autodesk\AdODIS\V1

1. Right-click:

RemoveODIS.exe

1. Select Run as administrator

Install the Latest ODIS Release

Procedure

1. Download the latest ODIS package from Autodesk
2. Install it manually
3. Restart Windows

Step 6: Reinstall Autodesk Licensing Service

Licensing failures are among the most common causes of installation errors.

Remove Existing Licensing Service

Procedure

1. Navigate to:

C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing

1. Run:

uninstall.exe

as Administrator

Install the Current Licensing Service

Procedure

1. Download the latest Autodesk Licensing Service package
2. Install it manually
3. Restart Windows

Step 7: Remove Corrupted Autodesk Components

For modern AutoCAD releases, Autodesk no longer relies on the legacy Autodesk Uninstall Tool that existed in older generations of products.

Use Autodesk Access or Windows applications management instead.

Remove Existing Autodesk Products

Procedure

1. Open:

Settings → Apps → Installed Apps

1. Uninstall:
2. AutoCAD
3. Autodesk Access
4. Autodesk Material Libraries
5. Autodesk Single Sign-On components
6. Autodesk Identity Manager
7. Restart Windows

Step 8: Resolve Error 1603

Error 1603 is the most common installation failure.

Typical causes include:

• Previous Autodesk remnants
• Registry conflicts
• Permission problems
• Corrupted MSI data
• Insufficient free space on C:\

Run Microsoft’s Install and Uninstall Troubleshooter

Procedure

1. Download Microsoft’s official Program Install and Uninstall Troubleshooter
2. Scan for Autodesk entries
3. Remove problematic registrations
4. Restart Windows

Remove Remaining Autodesk Folders

Procedure

Delete:

C:\Program Files\Autodesk\
C:\Program Files (x86)\Autodesk\

Delete user-specific folders:

C:\Users\%USERNAME%\AppData\Local\Autodesk\
C:\Users\%USERNAME%\AppData\Roaming\Autodesk\

Important

If other Autodesk products remain installed, do not remove shared Autodesk folders indiscriminately.

Examples include:

• Revit
• Inventor
• Civil 3D
• Maya
• 3ds Max

Remove only folders associated with the affected AutoCAD version.

Clean Autodesk Registry Keys

Procedure

1. Open:

regedit

1. Back up the registry
2. Remove:

HKEY_CURRENT_USER\Software\Autodesk

HKEY_LOCAL_MACHINE\Software\Autodesk

1. On 64-bit systems also inspect:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Autodesk

1. Restart Windows

Verify Drive Permissions

Procedure

1. Right-click the installation drive
2. Open:

Properties → Security

1. Verify:
2. SYSTEM = Full Control
3. Administrators = Full Control

Step 9: Resolve Error 4000

Error 4000 typically appears when Autodesk cannot access public Windows folders.

Verify Public Documents Exists

Procedure

1. Navigate to:

C:\Users\Public\

1. Confirm that:

Documents

exists

1. Verify the actual path:

C:\Users\Public\Documents

1. Recreate the folder if missing
2. Restore permissions

Step 10: Check OneDrive Folder Redirection

This is one of the least documented causes of installation failures.

AutoCAD and Autodesk services often expect local profile folders.

Problems occur when:

• Documents is redirected to OneDrive
• Desktop is redirected to OneDrive
• OneDrive synchronization is paused
• OneDrive authentication has expired

In these situations Autodesk may fail while attempting to access profile data, support files, local customization folders, or startup resources.

Verify Folder Locations

Procedure

1. Right-click:
2. Documents
3. Desktop
4. Pictures
5. Open:

Properties → Location

1. Verify that paths are valid and accessible

Correct any broken redirections before installing AutoCAD.

Step 11: Repair Microsoft Dependencies

AutoCAD depends heavily on Microsoft runtime libraries.

Repair Visual C++ Redistributables

Do not uninstall every Visual C++ package on the computer.

Many older applications depend on older runtimes.

Focus on modern packages.

Procedure

1. Open:

Programs and Features

1. Locate:

Microsoft Visual C++ 2015-2022 Redistributable

1. Repair or reinstall:
2. x64 version
3. x86 version
4. Restart Windows

Repair .NET Framework

Windows 10 and Windows 11 include .NET as a Windows component.

You cannot fully uninstall modern .NET Framework versions through normal methods.

Disable and Re-enable .NET Features

Procedure

1. Open:

Turn Windows features on or off

1. Disable:

.NET Framework Advanced Services

1. Restart Windows
2. Re-enable the feature
3. Restart again

Use Microsoft’s .NET Framework Repair Tool

If .NET problems persist:

Procedure

1. Download Microsoft’s official .NET Framework Repair Tool
2. Run the repair utility
3. Restart Windows

Step 12: Check Controlled Folder Access

Windows Defender’s ransomware protection can silently block Autodesk installers.

Verify Controlled Folder Access

Procedure

1. Open:

Windows Security

1. Open:

Virus & Threat Protection

1. Open:

Ransomware Protection

1. Check:

Controlled Folder Access

Temporarily disable it or create exclusions for:

• Setup.exe
• Autodesk Access
• ODIS
• AdskLicensing

Step 13: Check User Profile Names

Certain installers and scripts still encounter issues with special characters in Windows usernames.

Examples:

C:\Users\José\

C:\Users\François\

C:\Users\محمد\

Create a Temporary Administrator Account

Procedure

1. Create a new local Administrator account
2. Use only standard English characters
3. Sign in with the new account
4. Run the installation again

Step 14: Verify TLS, SSL, Proxy, and Network Settings

Autodesk cloud services require secure communication.

Verify Date and Time

Procedure

1. Open Windows settings
2. Enable:

Set time automatically

Verify TLS Connectivity

Ensure TLS 1.2 communication is functioning properly.

Older Windows images sometimes have TLS-related issues that prevent Autodesk downloads and authentication.

Disable Unnecessary Proxy Servers

Procedure

1. Open:

Settings → Network & Internet → Proxy

1. Disable unnecessary proxy settings

Step 15: Use Browser Download Instead of Install Now

The Browser Download method is significantly more reliable than the streaming installer.

Download the Full Installation Package

Procedure

1. Open Autodesk Account
2. Navigate to your AutoCAD download page
3. Select:

Browser Download

instead of:

Install Now

Extract Locally

Extract the package to a local folder such as:

C:\Autodesk_Install

Avoid These Locations

Do not install from:

• OneDrive folders
• Dropbox folders
• Google Drive folders
• Network shares
• NAS devices
• Encrypted drives

Use a local SSD or HDD.

Step 16: Review Installation Logs

Installation logs often reveal the exact component that caused the rollback.

Primary Log Locations

Check:

%temp%

C:\Autodesk

%localappdata%\Autodesk\ODIS

C:\Users\%USERNAME%\AppData\Local\Autodesk\ODIS

Most Important Log Files

Look for:

Summary.log

This file usually identifies the component responsible for the rollback.

Also review:

Setup.log

which records installation initialization and package activity.

For MSI failures, search for files such as:

AutoCAD_2026_install.log

or similar version-specific installer logs.

Search inside logs for:

• Error
• Failed
• Rollback
• MSI
• Licensing
• Return Code
