  4. Uncheck the box that says “Automatically check for updates.”
  5. Click on “Apply” and then “OK” to save the changes.

By following these steps, you have effectively disabled AutoCAD’s automatic update feature. However, this method only prevents AutoCAD from checking for updates; it does not block the update process entirely. To ensure complete blocking of AutoCAD updates, we will explore additional methods.

Blocking AutoCAD Updates via Windows Firewall

Another effective way to block AutoCAD updates is by using the Windows Firewall to restrict network access for the AutoCAD update process. Follow these steps to achieve this:

  1. Press the Windows key + R to open the Run dialog box.
  2. Type “wf.msc” and press Enter to open the Windows Firewall with Advanced Security.
  3. In the Windows Firewall window, click on “Outbound Rules” in the left-hand sidebar.
  4. Click on “New Rule” in the right-hand sidebar to create a new outbound rule.
  5. Select “Program” and click “Next.”
  6. Choose “This program path” and browse to the AutoCAD installation folder (typically located in C:\Program Files\Autodesk\AutoCAD [version]).
  7. Select the AutoCAD executable file (e.g., acad.exe) and click “Open.”
  8. In the “Action” section, choose “Block the connection” and click “Next.”
  9. Select the network types to which this rule applies (usually leave the default options selected) and click “Next.”
  10. Provide a name for the rule (e.g., “Block AutoCAD Updates”) and an optional description.
  11. Click “Finish” to create the rule.

By configuring the Windows Firewall to block outbound connections from AutoCAD, you effectively prevent the software from accessing the update servers. This method ensures that AutoCAD updates are completely blocked.

Utilizing Third-Party Firewall or Antivirus Software

In addition to the Windows Firewall, you can also utilize third-party firewall or antivirus software to block AutoCAD updates. Many security software solutions offer advanced features to manage network connections and block specific programs from accessing the internet. Consult the documentation or online resources for your preferred security software to learn how to create rules to block AutoCAD updates.

Isolating AutoCAD Installations from the Internet

If you have multiple AutoCAD installations in a networked environment and want to block updates centrally, you can consider isolating the AutoCAD installations from the internet. This can be achieved by implementing network segmentation or using a firewall appliance that restricts internet access for specific machines or subnets. By preventing internet connectivity for the machines running AutoCAD, you effectively block any update attempts.

Additional Considerations

When blocking AutoCAD updates, there are a few important considerations to keep in mind:

Ensure that your system is protected through other means, such as regular antivirus updates and secure network configurations.
  • Compatibility: Some new AutoCAD features and functionality may be introduced through updates. By blocking updates, you may miss out on these enhancements. Consider the specific needs and requirements of your AutoCAD usage to determine if blocking updates aligns with your objectives.
  • Maintenance: It is essential to periodically review and update your blocking mechanisms to ensure they continue to be effective. AutoCAD or related software updates may introduce changes that could bypass previously established blocking rules. Stay vigilant and adapt your blocking strategies accordingly.


1. Can I block AutoCAD updates without disabling the software’s functionality?

Yes, you can block AutoCAD updates without completely disabling the software. By following the methods described in this article, such as disabling automatic updates within AutoCAD or using the Windows Firewall to block network access for the update process, you can prevent updates from being applied while still retaining the full functionality of AutoCAD. It is important to note that blocking updates may leave your system vulnerable to security risks and may limit access to new features and improvements introduced through updates. Therefore, carefully consider your specific needs and priorities before deciding to block AutoCAD updates.

2. Will blocking AutoCAD updates affect the compatibility of my files with other versions?

Blocking AutoCAD updates should not directly affect the compatibility of your files with other versions of the software. AutoCAD is designed to maintain backward compatibility, allowing files created in older versions to be opened and edited in newer versions. However, it is worth noting that updates often introduce new features and functionality that may not be available in older versions. If you frequently collaborate with others who are using a different version of AutoCAD, it is advisable to communicate and ensure compatibility by saving files in compatible formats or using intermediary file exchange methods.

3. Can I selectively block specific AutoCAD updates while allowing others?
