Download

Download the latest version from www.linkcad.com/download. A free trial is available — no registration required to evaluate.

Installation Steps

Windows

1. Run the downloaded installer
2. Accept the license agreement
3. Choose an installation directory (default: C:\Program Files\LinkCAD)
4. Select components — the Python scripting extension is optional
5. Click Install and wait for completion
6. Launch LinkCAD from the Start Menu or desktop shortcut

Linux — .deb (Ubuntu/Debian)

sudo dpkg -i linkcad-*.deb

If there are missing dependencies, resolve them with:

sudo apt-get install -f

Launch LinkCAD from your application menu or run:

linkcad

Linux — .rpm (Fedora/RHEL/openSUSE)

sudo rpm -i linkcad-*.rpm

Or using dnf:

sudo dnf install linkcad-*.rpm

Linux — AppImage (any distribution)

The AppImage bundles all dependencies and runs on any modern 64-bit Linux distribution without installation.

chmod +x LinkCAD-*.AppImage
./LinkCAD-*.AppImage

Optionally integrate into your desktop by running the AppImage with --install (if supported by your desktop environment) or by creating a .desktop entry manually.

Upgrading from a Previous Version

Windows

Install the new version over the existing installation. Your settings, session files, and license are preserved automatically.

Linux

Replace the existing package using the same method you used to install it. Your settings in ~/.config/LinkCAD are preserved.

Tip

LinkCAD checks for updates on startup. You can also check manually via Help → Check Updates.

Silent Installation

For enterprise deployment on Windows, LinkCAD supports silent installation:

LinkCAD-Setup.exe /S /D="C:\Program Files\LinkCAD"

Trial Version

LinkCAD runs as a fully functional trial after first launch. After purchasing a license, enter your Registration Code to convert the trial into a registered version. No reinstallation required.

Uninstallation

Windows

Uninstall via Settings → Apps → LinkCAD or run the uninstaller from the installation directory. User settings stored in %APPDATA%\LinkCAD are preserved unless manually removed.

Linux — .deb

sudo dpkg -r linkcad

Linux — .rpm

sudo rpm -e linkcad

Linux — AppImage

Simply delete the .AppImage file. No system changes were made during installation. Settings in ~/.config/LinkCAD can be removed manually.
