Cannot install/upgrade 5.0.6

Recommended Posts



Have been running Paint.net perfectly fine for many years and absolutely love it. :)

Recently it attempted to automatically update to 5.0.6 and it failed due to an internal crash in .NET


As a software developer, I already have the .NET 7 SDK installed (along with Visual Studio 2022 etc).


I use multiple machines and the exact same issue has happened on all of them :(


I've attempted to use the web installer, MSI installer, x64 installer directly, all of which fail.

I have ensured there is no trace of Paint.net installed anywhere.


The error reported from the downloader is "Installation of paint.net failed (-1073741819, 0xC0000005)


Looking in the Event Viewer, shows 2 entries.

1. .NET Runtime

Application: SetupFrontEnd.exe
CoreCLR Version: 7.0.523.17405

I have uninstalled the .NET 7 SDK and reinstalled it to no avail.


I suspect this is caused by my machines being development boxes? Any help would be appreciated.

This has nothing to do with the .NET 7 SDK being installed. Paint.NET uses Self-Contained Deployment which means it uses a local copy of .NET that it comes with.


As for the error, I have no idea. It's come up a handful of times (search the forum for 0xC0000005). It's probably some rare/niche system or hardware configuration issue that Microsoft doesn't know about. My guess would be you have some other software installed that's interfering with things.
