This article provides instructions on installing the prerequisite software necessary to run the app on Windows 10 or 11.
Installing the app on Windows 7/8 (Legacy Support).
To run our Windows app on your device, you must install .NET Framework version 4.7.2 or higher.
If you have kept your machine up to date with Microsoft’s Windows Update service, you likely already have the latest .NET Framework installed, and you have nothing further to do.
However, should you find that your app is failing to start, or if you’re unsure whether you have a higher enough .NET version installed, follow the steps below to download and install the latest .NET Framework version.
At the time of writing, the latest .NET Framework is 4.8, so our screenshots below portray the installation of that version.
Download the latest .NET Framework
On your Windows device, open your web browser (e.g., Chrome) and head to the link below:
https://dotnet.microsoft.com/download/dotnet-framework/thank-you/net48-web-installer
You should see a page similar to the picture below, and the download should start immediately.
Start the Installer
When using Chrome as your web browser, your download should appear in the bottom left corner of your screen, and you can click on it to open it.
If you use a different browser, you may need to go to Windows Explorer and navigate to your Downloads folder. Look for the file that starts with “NDP” (e.g., ndp48-web.exe) and click it to start the installer.
Should you see a prompt like the picture below, click “Yes” to allow the installer to run on your machine:
Follow the Prompts
When the installer starts, you may see a message like this:
The above message is good news – you already have the latest .NET Framework installed 
You can just quit the installer and proceed to run your Windows app.
If you do not see the above message, that’s all good, too – just follow the installer’s prompts to get the .NET Framework installed.
Job done. Head over to your Windows app and start it up!
