I am using AutoCAD Civil 3D 2008 on an HP Pavilion dv7-1285dx laptop with Windows Vista. This morning I tried opening a dwg file I was editing on Friday, and AutoCAD crashed and gave me this message: "FATAL ERROR: Unhandled Access Violation Reading 0x0038 Exception at 59522e00h". I had just copied the file for a backup, and the copy also crashed AutoCAD. My previous backup, from Friday, opened just fine, but is missing a day's work.

I tried restarting my system, but that didn't work. Per a forum comment, I tried typing "RECOVER" at the command line of Civil 3D and choosing the problem file. AutoCAD found problems in the file, and said it fixed them, but when I open the file, none of my surfaces/alignments/etc. are shown in the Prospector. In fact, my alignment and stations don't even show in the drawing itself. Additionally, I get a message saying, "This drawing was created with a newer version of Civil 3D. All entities created by Civil 3D within the drawing are in a proxy state. Additionally, all commands, settings, and displays of Civil 3D are disabled for this drawing."

Cause

We've been seeing this issue from time to time with AutoCAD and AutoCAD Civil 3D 2017 installations. A quick fix from AutoCAD Service Pack 1 will take care of the problem.

Solution

1. You might see the error message pictured to the left as well.

Click No to close the error message.

2. Follow this link to Autodesk's AutoCAD 2017 Service Pack 1 page.

3. Scroll down on the Service Pack 1 page until you see the download options pictured to the left.

Click the correct AutoCAD 2017 SP1 version for your computer (64-bit or 32-bit).

This step will actually require you to download and install two separate files When you click the download link, your browser will either prompt you to download multiple files or open a secondary pop-up window, which may be easily overlooked or hiding behind the browser. (What you see will depend on your browser settings.) You may need to poke around a bit to find them. See the images below for examples.

Using Google Chrome? You should see a message that the Autodesk site wants you to download multiple files. Click Allow.

Using Mozilla Firefox? You'll have two download windows, which may or may not be hidden behind the browser window. Click Save File in each message.

4. The following two files will download to your computer:

• AutoCAD_2017_SP1_Part_2_Genuine
• AutoCAD_2017_SP1_64bit

Take note of the file names, and save the files in a location where you can find them easily.

5. Run each of the files you downloaded. Allow a few minutes for the Service Pack to install and repair your installation.

Experiencing an "unhandled access error" when launching AutoCAD can be frustrating, but there are a few troubleshooting steps you can try to resolve the issue. Here are some suggestions:

1. Update AutoCAD: Ensure that you are using the latest version of AutoCAD available. Updates often include bug fixes and improvements that can help resolve compatibility issues.
2. Run AutoCAD as an Administrator: Right-click on the AutoCAD icon or shortcut and select "Run as administrator" from the context menu. This can provide the necessary permissions for AutoCAD to run without encountering access errors.
3. Disable User Account Control (UAC): Temporarily disable UAC on your computer and then try launching AutoCAD again. To disable UAC, follow these steps:
   • Open the Control Panel on your computer.
   • Search for "User Account Control" in the search bar.
   • Click on "Change User Account Control settings."
   • Move the slider to the lowest position to disable UAC.
   • Restart your computer and try launching AutoCAD.
4. Repair AutoCAD Installation: Open the Control Panel, navigate to the "Programs" or "Programs and Features" section, and find AutoCAD in the list. Right-click on it and select "Repair" to repair the installation. This process will check for any missing or corrupted files and attempt to fix them.
5. Perform a Clean Reinstall: If the above steps do not resolve the issue, consider performing a clean reinstall of AutoCAD. Uninstall AutoCAD completely, including all associated files and folders, and then reinstall it using the latest installer.

Check System Requirements: Ensure that your computer meets the minimum system requirements for running AutoCAD. Verify that your hardware, operating system, and graphics card are compatible with the version of AutoCAD you are using.
