Trying to install paint.net but error coming up

Recommended Posts

Looks like NET Framework problem.

NET 3.0

Go to:

Control Panel > Programs and Features

Position things so that all Microsoft NET Framework

versions are visible.

Post a screenshot.

Will probably need to repair/re-install NET Framework.


Also, want to be sure that you have seen this thread.

Okay. Let's try this.

If you have an older version of Paint.NET installed still, uninstall it first.

Probably should then uninstall NET 4 first, then uninstall NET 3.5 SP1.

Run the Microsoft Installer Cleanup utility linked to here:


Download NET 3.5 SP1.


Reboot your PC.

Install NET 3.5 SP1.

Reboot again.

Install the current stable version of Paint.NET. v.3.5.4 (Not the beta)

If you're on Vista, only having .NET 4 installed currently won't work. Vista comes with .NET 3.0, which uses the 2.0 Runtime shared with .NET 3.5 SP1, and that tricks up the version binding at startup.

Install .NET 3.5 SP1 and you'll be good to go.

I'm looking to fix this for the final release but it may not be possible.
