Upgrades and LinkCAD 11
Your license runs every LinkCAD release published on or before your maintenance end date, at no extra charge. That includes LinkCAD 11 releases on Windows: LinkCAD 11 is not a separate purchase, and your existing registration code keeps working.
Enter your order number on the Download page to see that date and the newest release you may install. Later releases need renewed maintenance. Maintenance renewal: 15% of the current list price of your configuration per year, if renewed without interruption. Lapsed maintenance: quoted individually.
One LinkCAD license covers all platforms, Windows and Linux; there is no per-platform purchase. LinkCAD 11 on Linux is activated online: write to sales@linkcad.com with your order number.
Evaluating an upgrade to LinkCAD 11
Still on an older LinkCAD? Find out what LinkCAD 11 does with your files before you decide.
On Windows, LinkCAD 11 installs next to LinkCAD 10 and leaves it untouched. Check your order on the Download page first: if your maintenance covers LinkCAD 11, it is already yours.
If it does not, write to sales@linkcad.com with your order number and the conversion you run most. We will reply with a quote and tell you how to evaluate LinkCAD 11 with your files. Maintenance renewal: 15% of the current list price of your configuration per year, if renewed without interruption. Lapsed maintenance: quoted individually.
Trial
On Windows, the download is the trial: it runs for 5 days from the first start, and the LinkCAD 11 trial includes all options.
On Linux, request the trial from within LinkCAD with Request / Extend Trial…: the request goes to the license server online and may need approval before the trial starts.
Need more time to evaluate? Write to sales@linkcad.com before it ends, with the serial number LinkCAD shows, and ask for an extension.
If your trial ends while your order or purchase order is being processed, tell us and we will extend it.
Network licenses
Seats are concurrent: install LinkCAD on as many computers as you like; up to 3 (Network Lite) or 30 (Network) can run it at the same time.
The license is issued for one shared folder on your network: you send us its path and we send a license file. Moving the server or renaming the share needs a new license file, so contact support@linkcad.com before you change it.
Network licenses cover users at one site; ask sales about additional sites or VPN access. For more than 30 users, contact sales@linkcad.com.
Virtual machines, terminal servers and remote desktop require a network license, because they can be used by several people.
Moving a license to another computer
On Windows, a Single User license moves with the built-in transfer function while both computers run LinkCAD: enter the new computer’s serial number on the old computer, and LinkCAD shows the registration code for the new computer and removes the license from the old one.
If the old computer no longer works, or you use LinkCAD 11 on Linux, write to support@linkcad.com with your order number.
Delivery and activation
After payment, or once we accept your purchase order, we email the registration code to the ordering contact, or to the end-user email named on the order, within 1–2 business days.
In LinkCAD 11, enter the code under Help → License…, where the serial number of the computer is also shown. In LinkCAD 10, the serial number is under Help → About. Quote the serial number and your order number whenever you contact us.

One LinkCAD license covers all platforms, Windows and Linux; there is no per-platform purchase.
