Side-loading Applications
Because 1Edit is installed as a side-loaded application (not from the Microsoft app store) then your operating system must be licensed and enabled for side-loading.
Enable side-loading of trusted applications
Before installing, every machine must have set the Allow all trusted applications to install Group Policy setting, which your IT department can help you with.
If your IT department doesn’t use a group policy, then each machine can be configured to allow side loading by ensuring Developer mode is enabled on the machine in question.
Note: For more information on Developer mode and side-loading applications within Windows, please see the official Microsoft documentation.
