Download TopoMan CAD

Windows, Linux, macOS and Android, and the browser with nothing to install. On iPhone and iPad, as a web app

How to install it

Four ways in: on Windows, the store is the least trouble; on Android, Google Play.

On iPhone and iPad, as a web app

The iPhone and iPad app will come later. In the meantime, the web version installs from Safari and sits on the Home Screen like any other app: with its icon, full screen and offline from the second time you open it. It is the same program, with the same DWGs.

How to install it

  1. Open app.topoman.net in Safari.
  2. Tap the Share button (the square with an arrow pointing up). On iOS 26 it is inside the "···" button.
  3. Choose "Add to Home Screen" and confirm. If "Open as Web App" shows up, leave it on.
  4. Open it from its icon. The first time it downloads the program; from the second it works offline.
Open app.topoman.net

What is different on iPhone and iPad

  • DWG, DXF and PDF files open with "Open file", from the Files app, iCloud Drive or wherever you keep them. Tapping a file in Files does not open TopoMan CAD.
  • Saving is downloading: the file ends up in Files, in the Downloads folder.
  • PDFs can be read, marked up, filled in and have their pages rearranged, but they are not signed or printed from the app: to print one, save it and open it in Files.
  • 3D Architecture and 3D Modeling can be viewed and walked through; they are designed on the computer.
  • If you delete the app from the Home Screen, that device counts as a new one for the license.

What changed in each version: the changelog

Windows will warn you, and it is not a virus

These executables are not signed with a paid certificate, so SmartScreen shows a blue screen saying it protected your PC. Click "More info" and then "Run anyway". If you would rather not see that warning, install it from the Microsoft Store: there the package is signed by Microsoft.

Download from the Microsoft Store

On a Mac, the first time it opens from Settings

  1. Open the DMG and drag TopoMan CAD to the Applications folder. It is a single one for any Mac, with an Apple chip (M1 or later) or Intel.
  2. Open it once. macOS will say it cannot check it for malware: it is not notarized by Apple, which is a paid process. Close the warning without moving it to the Trash.
  3. Go to System Settings › Privacy & Security, scroll down to "Security" and click "Open Anyway". Confirm with your password or Touch ID.
  4. From then on it opens like any other program.

Before you install

  • Windows 10 and 11: nothing else, on 64-bit, 32-bit or ARM.
  • Windows 7 and 8: use the files marked "Windows 7". They need the Visual C++ redistributable: it is below, under "If Windows 7 shows this error".
  • Windows on ARM: Windows 10 or later only.
  • Android: you have to allow installing from unknown sources, because the APK does not come from Play.
  • iPhone and iPad: there is no file to download. You install the web version from Safari: see "On iPhone and iPad", above.

What the checksum is for

It is the signature of the contents. If the one for the file you downloaded does not match the one here, the download was cut short or the file is not mine. On Windows you check it with: certutil -hashfile <file> SHA256

If Windows 7 shows this error

Windows error dialog: "The program can't start because VCRUNTIME140.dll is missing from your computer"

Windows 7 and 8 do not ship the Visual C++ libraries TopoMan CAD needs, and on launch they say "VCRUNTIME140.dll is missing". It is fixed once by installing the Microsoft redistributable: the same file you would download from their site, served from here so it is at hand.

Install the one matching your TopoMan CAD: x64 for the 64-bit build, x86 for the 32-bit one. If in doubt, install both; they do not get in the way. After that, TopoMan CAD opens normally.

Microsoft Visual C++ 2015-2022 redistributable, unmodified. Windows 7 needs Service Pack 1.

On everything you have

The same program and the same file. What you draw in the office opens on the phone, in the field.

  • Windows

    10 and 11, in 64-bit, 32-bit and ARM. And 7 and 8 too, with their own build

  • Android

    The whole application, with a touch interface and stylus. And with a monitor, keyboard and mouse, the desktop interface

  • Browser

    Nothing to install, and it works offline from the second visit

  • iPhone and iPad

    As a web app: add it to the Home Screen from Safari and it works offline. The app will come later

    How to install it

  • Linux

    AppImage and Flatpak, on x86_64 and ARM64

  • macOS

    Intel and Apple Silicon

The Microsoft Store requires Windows 10 or later. Windows 7 and 8 have their own build, which comes through the direct download.
