Installing Interviewer 

Interviewer runs your Network Canvas protocols and collects data in the field. You do not need any of the other Network Canvas applications to use it.

Interviewer comes in two supported versions, and you get them in different ways:

• Interviewer (beta) — runs in your web browser, with nothing to download. Open it at interviewer.networkcanvas.com, and optionally install it as a Progressive Web App (PWA) on a device you control for quick access and offline use. Built on the same platform as Fresco 4.0, it supports schema 8, is compatible with your existing protocols, and is recommended for new studies.
• Interviewer Classic — the established desktop and tablet app. Download and install it from the download page. Runs schema 7 protocols and works fully offline.

Using Interviewer in the browser

Open interviewer.networkcanvas.com in a modern web browser — there is no download or installation step, and the app always runs the latest version. To keep it handy on an interview device, use your browser's Install option (often shown as an install icon in the address bar, or "Add to Home Screen") to install it as a Progressive Web App. It then opens in its own window, appears alongside your other apps, and remains available offline.

We recommend a modern device with a high-resolution screen and ample memory. Performance may differ considerably depending on the power of the device you use, and a slow device can negatively impact the interview experience for your research participants, leading to poorer-quality data.

Installing Interviewer Classic

Interviewer Classic is the downloadable desktop and tablet app, available from the download page. Install it on any device you will use to interview participants.

System Requirements

Interviewer Classic is supported only when running on Windows 10 (1909) or newer, macOS 10.15.4 or newer, Android 10 or newer, and iPadOS 14.2 or newer.

We recommend a modern device, featuring a high-resolution screen (greater than 900 pixels effective vertical resolution), ample RAM, and dedicated graphics. Performance may differ considerably depending on the power of the device that you use, and you should be aware that this can negatively impact the interview experience for your research participants, leading to poorer quality data.

You may install and run the software on devices that do not meet these criteria, but we are unfortunately unable to offer support regarding technical issues if you do.

Windows

Visit the download page, and download the Windows version of Interviewer Classic.

Open the .exe file. You may be presented with a dialog that says the application cannot be run because it is from an unsigned publisher. This happens because our apps have not yet built up enough trust with Microsoft to automatically pass these filters. This will change as more users install our apps.

In order to continue to install the application simply click the "more info" text in the dialog. Then a "Run Anyway" button should appear. Once the application is installed it should open straight away. You should also be able to find the application in your program list from the start menu.

macOS

Visit the download page, and download the macOS version of Interviewer Classic. This is packaged in the form of a DMG disk archive.

When you double-click on the DMG file it will open a new Finder window with the application icon and a folder representing your computer's "Applications" folder. Drag the application into the Applications folder. If you are prompted for authentication and you do not have it, you can simply drag the application to anywhere underneath your home directory.

Once the application is installed you will need to double-click on the application icon to open the program.

Linux

We provide Linux packages in a variety of formats, and for both x86 and ARM architectures. Visit the download page, and click on the link for downloading Interviewer Classic on Linux. You will be redirected to the most recent release on GitHub, where you will find the package files themselves. Please refer to your distribution's documentation on which package formats are supported, and for specific installation instructions.

If you have difficulties installing or running these packages, please contact the project team.

Please note that we no longer support the SNAP package format, owing to difficulties with the build process. If you are using earlier versions of the software that were distributed in this format, please update to one of the currently supported packages.

Android

Installation on Android devices works the same as with any other Android app. Interviewer Classic can be found by opening the Play Store app, and searching for "Network Canvas Interviewer". Alternatively, you can visit the Play Store website, and initialize the installation on your devices from there.

Please note that Interviewer Classic requires Android version 10 or newer, and will work best with larger tablet devices (9.7"+). Installation is restricted to devices that meet these criteria.

If you cannot find Interviewer Classic in the Play Store, it is likely because your device is not compatible. If you believe your device should be compatible and you still cannot find the app in the Play Store, please contact us.

ChromeOS

If your ChromeOS device supports installing Android apps, you can install Interviewer Classic as usual through the Google Play Store. To do this, please see the instructions above for installing the app on Android.

Please note that only Interviewer Classic is specifically designed to work with ChromeOS, and only when run as an Android app. Running Interviewer Classic through Linux app compatibility is not supported at present.
