Note: System administrators should update .NET and other prerequisites on all client computers before upgrading or installing P6 Professional.
Ensure that you have required prerequisites before you attempt to run ClickOnce:
- A compatible version of Windows operating system.
Note: ClickOnce is only supported for Windows operating systems.
- .NET Framework
You must have administrator privileges on your machine to install some of the ClickOnce prerequisites. If you do not have the required version of .NET and do not have administrator privileges on your machine, then the ClickOnce installation will fail and you should contact your system administrator.
See https://docs.microsoft.com/en-us/dotnet/framework/deployment/guide-for-administrators for more information about .NET prerequisites. See document for more information on supported versions of Windows and .NET.
