Thank you, Ego Eram Reputo, for the post.
I installed and ran the Windows Installer CleanUp utility and then removed Paint.NET. I deleted the folder directory where the Paint.NET was installed to.
I ran Paint.NET 3.5.11 installation and it still gives me an error message saying:
"Paint.NET Setup Front-End has encountered a problem and needs to close. We are sorry for the inconvenience."
How can I fix the problem? Again thank you very much for the post.
