AutoCAD and Revit Freeze at "Signing In": Fix for the Autodesk Identity Manager Error

Why does the infinite loop happen when signing in to Autodesk?

The single sign-on (SSO) failure in products like AutoCAD or Revit is usually related to:

• Corruption in AdskIdentityManager: Autodesk's identity management utility (official documentation) can damage its configuration files.
• Conflicts with corporate proxies: According to Autodesk Support, restrictive network configurations interrupt the authentication handshake.
• Outdated component versions: The identity client requires periodic updates to maintain compatibility.

Step-by-step guide to resolving the lockup

1. Manually uninstall AdskIdentityManager

1. Close all Autodesk programs and your web browser.
2. Navigate to C:Program Files (x86)AutodeskAdskIdentityManager (or the equivalent path on 32-bit systems).
3. Delete the entire AdskIdentityManager folder.
4. Empty the recycle bin.

2. Standalone installation of the component

Download the updated installer from the Autodesk management portal or use this direct link:

3. Post-installation configuration

Step	Required action
