Can't launch my app because of 'you must install .NET Desktop Runtime' popup

Connor Frayne 20 Reputation points

Hi everyone,

I'm trying to run my application I've just installed on my computer but I'm having an issue with my .NET Runtime. I've been debugging this application in Visual Studio Community 2022 v17.10.2 and it works fine when I start it through Visual Studio but when I create an installer, install and run the application I get this popup.

I've attempted installs from both inno setup and Visual Studio Installer projects and neither work. I'm 1000% sure I have .net 8.0.6 Desktop Runtime x64. The Download link doesn't lead anywhere and the Download it now button just closes the popup(nothing is downloaded). Any ideas?

Thank you,

Connor Frayne

    Hello @Connor Frayne,

    Welcome to Microsoft Q&A forum.

    I think the error message is clear enough, the .NET Desktop Runtime is missing.

    I notice that you are 1000% sure that you have .NET 8.0.6 Desktop Runtime x64. I don’t doubt that, but maybe you can also try to install version 8.0.5. You can download here: .NET Desktop Runtime 8.0.5.

    Here’s what happens when I try to add a .NET Runtime installer as a perquisite for my VS Installer Project.

    Try to download ".NET Desktop Runtime 8.0.5 x64" file and put it under this directory: C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VisualStudio\BootstrapperPackages\net8desktopruntime_x64, rebuild your project, see if this error disappears.
