Which one do I need?

Windows

Excalibur View for Windows

Start here if you're on Windows. This is the program you open drawings in. Install it on each computer that needs it. It installs for that person without an administrator and puts itself in the Start menu. On its own it's free, forever, for one person doing any work you get paid for.

Windows 10 or 11, 64-bit
Download for Windows
macOS

Excalibur View for Mac

Start here if you're on a Mac. The same program, from the same source. Open the disk image and drag Excalibur View into Applications. One download runs on Apple Silicon and Intel. It's signed and notarized by Apple, so it opens on a double-click with no warning and no right-click trick.

macOS 11 Big Sur or later. Apple Silicon or Intel.
Download for Mac
Windows Server

The Office server

Only if two or more of you work off the same drawings. Install it once, on your server or any machine that stays switched on. The desktop apps on your network find it by themselves, Windows and Mac alike. Every Office feature runs free for 30 days from the first start, for any number of people, with no card. You don't need this to try the program.

Windows 10 or 11, Windows Server 2016 or later
Download the server

Both the app and the Office server are published, source-available under the Elastic License 2.0: github.com/cngmoney88/excalibur-view. Whoever approves software in your office can read what it does before it goes on a machine, and build it themselves if that's what your policy says. What the licence allows.

Older versions and what changed in each: release history. To hear when a new one is out, write to me. It's optional and the list isn't used for anything else.

Installing it on Windows

  1. Run the file. It installs to your user folder and opens.
  2. Windows will warn you. You'll get “Windows protected your PC.” Click More info, then Run anyway. The honest reason is that the Windows build isn't code-signed yet, so Windows has nothing to check it against. That's a real gap and it's being worked on. Until it's closed, don't take my word for the file: check the SHA-256.
  3. Drag a drawing set onto the window, set the scale, and start measuring.
  4. Already have a tool chest? Put the .bpx or .btx file in the profiles folder next to the program and it'll be there when you restart.

Installing it on a Mac

  1. Open the .dmg and drag Excalibur View into Applications.
  2. Open it from Applications, not from the mounted disk image. A disk image is read-only and the program can't finish setting itself up there.
  3. There is no Gatekeeper warning and no right-click-then-Open trick. It's notarized by Apple, so it just opens. If you do see a warning, something is wrong with the download and you should check the hash below.
  4. Drag a drawing set onto the window, set the scale, and start measuring.

What it runs on

Desktop app, WindowsWindows 10 or 11, 64-bit. Also Windows Server 2016, 2019, 2022 and 2025 with Desktop Experience, including over Remote Desktop.
Desktop app, macOSmacOS 11 Big Sur or later. One universal build for Apple Silicon and Intel. Signed with an Apple Developer ID and notarized.
Office serverWindows only, the same versions as above plus Server Core. Runs as a Windows service, so nobody has to stay signed in. Mac seats connect to it exactly as Windows seats do.
GraphicsNo graphics card needed.
UpdatesThey install themselves on both, checked against my signature before they run.

Checking what you downloaded

Run the line for your machine in the folder you downloaded to. The result should match the SHA-256 listed with the file above.

Worth being precise about what is signed and what isn't. The Mac build is signed and notarized by Apple, which is why it opens with no warning. The Windows build is not code-signed yet, which is why Windows warns you about it. Every update, on both platforms, is signed with a key only I hold and checked by your own copy before it installs, so this hand check is only for the first file you fetch yourself.

If a hash doesn't match, don't run the file, and tell me: hello@excaliburct.com.
