I had already tried to install Paint.Net v5.0 from the offline installer. I had exactly the same problem. Error message to have a more recent version of Windows. I unzip the zip file in a folder before launching the installation. After the installation, I launch Paint.Net from the shortcut of the start menu. I also tried directly from the folder "C:Program Files\paint.net" by running paintdotnet.exe. I had also disabled my Antivirus. Then i uninstalled Paint.Net and installed it again. Still the same error. Today I got the version 5.0.1. Still the same error message after installing the offline installer. I test with the portable version (in download folder) and it works !? 😉 . I copied the folder of the portable version to the installation folder (robocopy /MIR) . Still the same error. So I looked at the properties of paintdotnet.exe and i realized that I have a compatibility mode on Windows 7. By deactivating it, the software launches correctly. Here is the cause of the problem. The information of the compatibility mode is stored in the registry of the user (possible also in HKLM) : HKEY_USERS\SID_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers. This information persists in the registry even after uninstalling the software and/or deleting the file/folder. Voilà, subject solved. Thank you all for your help.

Hi, Thanks I just updated my Windows 10 22H2 from the October 2022 cumulative update build 19045.2130 to the January 2023 cumulative update build 19045.2486 and all other pending updates. Paint.NET 5 still doesn't launch and I still get the message that asks for a Windows 10 1809 / Windows 11 version or higher, which is the case (Windows 10 22H2) ?! Any other idea ? Thanks. Good day. Regards.

Hello, I have just updated Paint.Net version 4 to version 5. No problems during the upgrade, installation. But, I can't launch Paint.Net. It asks me to update my Windows version. I am under Windows 10 22H2 in French. How do I get past this warning message, this verification ? Thank you in advance and have a nice day.
