SketchUp 2016 was a milestone release—improving performance, adding the Offset tool, and refining the inferencing system. But its license key and authorization code system exists to protect the developers who built it. If you own a valid license, great—retrieve it. If not, explore SketchUp Free, Make 2017, or a modern subscription. The few dollars saved by piracy are never worth the cost of your security or integrity.

The heavy dust of the renovation site didn’t bother Elias half as much as the digital wall he’d just hit. He sat in his makeshift office—a plywood plank over two sawhorses—staring at his aging laptop. On the screen was the blue and white icon of SketchUp 2016
. To Elias, it wasn’t just old software; it was the only version that ran perfectly on his weathered hardware, and it held the intricate 3D blueprints for the heritage library restoration he was supposed to pitch in two hours.
He had just reinstalled the OS to speed things up, but now the program was demanding its soul back.
“Please enter your Serial Number and Authorization Code,” the prompt read.
Elias rifled through a stack of yellowing invoices and coffee-stained notebooks. He remembered buying the perpetual license back when "Pro" meant you owned the pixels you worked on. He found a faded printout from years ago. With trembling fingers, he typed in the string:
He hit enter. The "Invalid License" red text felt like a physical blow.
He tried again, squinting at the ink. Was that a '0' or an 'O'? A '1' or a lowercase 'L'? The clock on the taskbar ticked forward. If he couldn't open the file, he couldn't show the client how the sunlight would hit the reading room at 4:00 PM.
He took a breath, cleared the fields, and carefully re-entered the codes from a different email backup he’d found on his phone. He clicked 'Add License'
The spinning wheel of death lasted five seconds—long enough for Elias to consider a career in masonry instead of architecture. Then, the red text vanished. A simple green checkmark appeared. “License successfully added. Welcome back, Elias.”
The workspace opened, revealing the skeletal beauty of the library’s rafters. Elias exhaled, grabbed his hard hat, and headed toward the site. The old tools, it seemed, still had plenty of work left to do. compatibility settings for older software?

SketchUp 2016 License Key and Authorization Code: A Complete Guide
If you are a designer, architect, or hobbyist looking back at SketchUp 2016, you’re likely trying to revive an older workflow or access legacy files on a machine that doesn't support the newest versions. SketchUp 2016 was one of the last versions to offer a robust perpetual license before the industry-wide shift to SaaS (Software as a Service).
In this guide, we will break down how the licensing system worked for this version and what your options are today. Understanding the SketchUp 2016 Licensing System
Back in 2016, SketchUp Pro used a two-part credential system to activate the software:
The License Key: A unique alphanumeric string (e.g., beginning with "QA", "RA", or "SA").
The Authorization Code: A secondary code used to "unlock" the license on a specific machine.
Unlike modern versions where you simply sign in with a Trimble ID, the 2016 version required these manual entries to transition from "Trial Mode" to "Pro Mode." Where to Find Your Original License
If you previously purchased SketchUp 2016 Pro, your license information is not lost. You can usually recover it through these methods:
Confirmation Email: Search your inbox for "SketchUp License" or "Trimble." The original email contained both the serial number and the authorization code.
The License Manager: If you still have SketchUp 2016 installed on an old computer, go to Help > License > License Info to view your serial number.
Trimble License Lookup: Trimble provides a legacy "License Lookup" tool on their website. By entering the email address used at the time of purchase, you can have your old credentials resent to you. Can You Buy a SketchUp 2016 License Today?
The short answer is no.Trimble officially discontinued the sale of perpetual licenses (including SketchUp 2016, 2017, and 2018) years ago. Authorized resellers are also prohibited from selling these legacy keys.
Warning: Beware of websites claiming to sell "cracked" license keys or "generators" for SketchUp 2016. These files often contain malware or ransomware and, legally, do not provide a valid license for professional use. Technical Hurdles for SketchUp 2016 in 2024+
Even if you have a valid license key, running SketchUp 2016 today comes with challenges:
Operating System Compatibility: SketchUp 2016 was designed for Windows 7/8 and OS X Yosemite. It may crash or exhibit "invisible menu" bugs on Windows 11 or the latest macOS.
The 3D Warehouse: The 3D Warehouse no longer supports SketchUp 2016. You will likely see a "Connection Error" or a blank screen when trying to download models directly into the app.
Extension Warehouse: Most modern extensions (Plugins) require a newer Ruby API version than what SketchUp 2016 provides. Modern Alternatives
If you can’t get your 2016 license to work, consider these paths:
SketchUp Free: A web-based version that is surprisingly powerful for hobbyist use.
SketchUp Go: A mid-tier subscription that works on iPad and web.
SketchUp Pro Subscription: The current standard, which includes the desktop application, LayOut, and full 3D Warehouse access.
SketchUp 2017 Make: This was the last "Free" desktop version. While also unsupported, it is often more stable on modern hardware than the 2016 version.
