AutoCAD Civil 3D is one of the most widely used software tools among civil engineers globally. Much of the infrastructure that we see around us has likely been planned using AutoCAD Civil 3D at some stage. Be it buildings, airports, railways, roads, houses, hotels, or any other infrastructure we come across, a significant portion of their planning was likely done with this software. Its prevalence and influence are enormous. While AutoCAD Civil 3D is an indispensable software, it comes at a fairly high cost. This is due to the comprehensive features it offers and its array of unique attributes.

It's crucial to keep your software license key/product key safe and readily available when you purchase it, as without it, you won't be able to activate the software during registration. Quite often, we find ourselves in a situation where we've lost the product key, but the software is already registered on our computer. In such cases, you should attempt to retrieve the key from the software itself, as getting the license key back from the company can be a long and cumbersome process that may take weeks and might require various proofs of purchase.

In this article, we will guide you on how to find your Autodesk Civil 3D serial number and product key. Make sure to read through the entire process as each step is important.

How to find your serial number and product key (manual method)

Given that an annual license for Autodesk Civil 3D costs around $2,500, it's definitely not worth losing the product key. So here are some ways to retrieve a lost serial number and product key from the Autodesk Civil 3D software itself.

Method 1: Using the Orca MSI Editor Tool

Orca MSI Editor is a software that comes bundled with the Windows SDK, allowing you to edit the MSI files of any software installed on your computer. MSI files are typically used by the Windows operating system to store and create databases of applications. Each application has its separate database. By accessing the Autodesk Civil 3D application's database through this method, you can then extract the product key and serial number from there.

Here are the steps to follow:

Step 1: Download the Orca MSI editing tool, which is available only as part of the Windows SDK. You will therefore need to install the Windows SDK, and then install Orca.exe from it.

Step 2. Once Orca is installed and launched, navigate to the Autodesk MSI file. It is usually located in the x64\acadcivil3d folder.

Step 3: Right-click on the file and select "Edit with Orca." In the left pane, click on Property Sheets, and then use the Find and Replace option.

Step 4: In the Find and Replace dialog, search for ProductCode.

Step 5: The product code will be displayed in the "Value" field.

Method 2: Using the Registry Editor

Alternatively, you can obtain the Autodesk Civil 3D product key using the Registry Editor in Windows. Here are the steps:

Step 1: Press the Win+R keys to open the “Run” dialog box.

Step 2: Type Regedit to open the Registry Editor.

Step 3. In the Registry Editor, navigate to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\UPI2

Step 4. Your Autodesk Civil 3D product key is located in this path.

Step Five: Copy it and write it down somewhere.

Please understand that both of these methods are very complex and can only be done if you are a computer expert. We recommend using a safer and more efficient software to find your Autodesk Civil 3D serial number and product key.
