Internal Error 2602 in AutoCAD is a technical failure typically encountered during the installation or startup phase. While "high quality" often refers to a specific AutoCAD graphics setting (High Quality Geometry) that can cause stability issues, Error 2602 itself is more commonly linked to system compatibility and installer failures. Core Causes of Error 2602
The following factors are the most likely triggers for this specific error:
System Architecture Mismatch: Attempting to install a 64-bit version of AutoCAD on a 32-bit operating system.
Installer Type: Using the "Install Now" or "Web Installer" option, which often fails due to simultaneous downloading and installing.
Permissions & Security: Lack of administrative privileges or interference from antivirus software and User Account Control (UAC).
Graphics Compatibility: Outdated graphics drivers or hardware that does not support modern requirements (e.g., DirectX 11/12), leading to failures when the software attempts to initialize high-quality geometry. Troubleshooting & Fixes 1. Verify System Compatibility
Ensure your hardware meets the minimum system requirements for your specific AutoCAD version.
Right-click "This PC" (or "My Computer") and select Properties.
Confirm if your OS is 64-bit or 32-bit and match it to your installer. 2. Use "Browser Download" Method
Avoid the standard web installer. Instead, log in to your Autodesk Account and use the Browser Download option. This downloads the full installation package first, preventing errors caused by interrupted connections during setup. 3. Update Graphics Drivers
Since "high quality" errors are often related to the GPU, ensure you are using an Autodesk-certified driver: Visit the Autodesk Certified Graphics Hardware site.
If your current driver is certified but the error persists, try turning off Hardware Acceleration temporarily by typing GRAPHICSCONFIG in the AutoCAD command line. 4. Clear Graphics Cache
Corrupted cache files can cause internal errors during high-quality rendering.
Set the system variable CACHEMAXFILES to 0, restart AutoCAD, and then set it back to 256. internal error 2602 autocad high quality
Alternatively, delete the contents of the GraphicsCache folder located in your local AppData. 5. Reset AutoCAD to Default
If the error occurs after a successful installation, resetting the software can clear corrupted user profile settings: Go to the Windows Start Menu.
Find your AutoCAD folder and select Reset Settings to Default.

Does this error happen during installation or while using a specific command?
Which version of AutoCAD (e.g., 2024, 2025) are you running? Are you using a 4K/High-DPI monitor?
If you need to get the drawing out right now, the fastest workaround is to bypass the printer queue.
Why this works: It takes the physical printer driver out of the equation. AutoCAD creates the PDF; the PDF viewer handles the printer communication.
If Error 2602 appears only when plotting specific drawings, you likely have a corrupt entity—usually a Hatch pattern.
Gradient fills are notorious for causing 2602 errors on older hardware. Try converting gradient fills to solid colors or standard non-gradient hatches.
To fix a problem, you must understand its origin. In AutoCAD’s architecture, Error 2602 belongs to the ARX (AutoCAD Runtime eXtension) layer. Specifically, it occurs when the Database Resolver fails to map an object’s handle (a unique hex ID) to its physical memory address.
Three root causes dominate:
Crucially, Error 2602 is rarely a problem with the .DWG file itself. Replacing the drawing often does nothing. The problem lives in your working environment.
