Once fixed, implement these best practices to avoid seeing this dreaded error again:
If the error is consistent with a specific file on multiple machines, send that file to Autodesk. If it’s machine-specific (works on other PCs), reinstall AutoCAD completely using the Microsoft FixIt tool first, then a clean uninstall/reinstall.
Typical root cause summary:
Error 2602 usually means a drawing element cannot be processed during the plotting pipeline. In 80% of cases, RECOVER + PURGE + switching to DWG to PDF.pc3 solves it. The remaining 20% involve a corrupt graphics driver or a damaged OLE object.

Internal Error 2602 in AutoCAD typically occurs during installation or update processes, often triggered by a failure to copy or access specific internal system files (such as __gGeometry.dll) from a network installation point. It is a standard Windows Installer (MSI) error indicating that a required file cannot be found in the specified cabinet or installation source. Common Causes
Corrupt Installation Package: The update file or installation source may be damaged or incomplete.
Network Deployment Issues: Installing from a network share where a patch (like AutoCAD 2019 Update 1.2) has been added can cause the installer to fail when looking for "Additional Files". Once fixed, implement these best practices to avoid
Environment Conflicts: Outdated .NET Framework versions or insufficient disk space can block the installation from completing.
Permission Restrictions: The installer may lack the necessary administrative rights to register specific .dll components. Recommended Solutions
Redownload and Re-install: If the error occurs during an update, redownload the update file directly from the Autodesk Account portal rather than using a network share.
Repair via Control Panel: Use the Windows "Uninstall/Change" option to run a Repair or Reinstall of the main AutoCAD application before applying the update.
Use Microsoft Troubleshooter: Run the Microsoft Program Install and Uninstall Troubleshooter (Fix-It tool) to clear registry keys that might be blocking the installation.
Update Core Components: Ensure your .NET Framework is up to date and that you have installed the latest Autodesk Desktop Licensing Service.
New Windows Admin Account: Creating a new Windows user with full administrator rights and running the installation from there can bypass account-specific profile corruption.

How to fix it:
Internal Error 2602 in AutoCAD typically occurs during the installation or updating of the software, specifically when the MsiInstaller fails to register a critical file (often a .dll). This error is frequently triggered by corrupted installation packages, insufficient user permissions, or outdated system components like the .NET Framework. Common Causes of Error 2602
Corrupted Installer: A glitch during the download or extraction of the AutoCAD update or installation package.
Permissions Issues: The user account lacks the administrative rights necessary to write files to system directories.
Outdated .NET Framework: AutoCAD relies heavily on specific versions of the Microsoft .NET Framework; if this is outdated or damaged, the installer may trigger a 2602 error.
Software Conflicts: Third-party antivirus or security software may block the installation of specific DLL files, misidentifying them as threats.
Insufficient Disk Space: Lack of available space on the primary drive can interrupt the file registration process. Step-by-Step Solutions to Fix Internal Error 2602 1. Run as Administrator
Ensure you are logged into a Windows account with full administrative privileges. Right-click the AutoCAD installer or update file and select Run as Administrator to bypass restricted folder permissions. 2. Update Microsoft .NET Framework
Since Error 2602 is often linked to framework dependencies, verify you have the latest version:
Visit the Microsoft .NET Download page to find the latest version.
Restart your computer after installation before attempting the AutoCAD update again. 3. Disable Security Software Temporarily
Antivirus programs can sometimes block the MsiInstaller from registering specific DLLs. Temporarily disable your antivirus and Firewall.
Disable User Account Control (UAC) settings in the Windows Control Panel.
Retry the installation. Remember to re-enable your security software immediately afterward. 4. Clear Temporary Files and Free Up Space
Ensure your hard drive has enough free space beyond the minimum installation requirements.
Use the Disk Cleanup tool in Windows to remove temporary files.
Manually clear the contents of C:\Users\%USERNAME%\AppData\Local\Temp\. 5. Repair or Reinstall the AutoCAD Component
If the error occurs during an update, the base installation might be corrupted. Go to Control Panel > Programs and Features. Select your AutoCAD version and click Uninstall/Change.
Choose the Repair or Reinstall option within the Autodesk maintenance wizard. 6. Use the Microsoft Install/Uninstall Troubleshooter
If the 2602 error persists, a "ghost" installation may be blocking the process. Use the Microsoft Program Install and Uninstall Troubleshooter to automatically repair registry keys that prevent successful installation. Preventative Tips
Use Direct Download: Avoid using the "Install Now" method. Instead, download the full installer from your Autodesk Account using the Browser Download method.
Keep Windows Updated: Ensure all critical Windows updates are installed, as these often include necessary runtime libraries. dll file if the installer continues to fail? AutoCAD 2019 1.2 Update Error Message - Forums, Autodesk
