[Can't install problem with .NET Framework]

Here is the additional system information.

I wish someone would look at this post and reply, please help.  I miss using my Paint.net program, and I don't want to reset to factory (which is my last hope).

[Can't install problem with .NET Framework]

I have had Paint.Net on this computer before.  The problem I am having is I had to reformat and now in re-installing I am getting an error, the files download fine, but it says .NET Framework cannot be installed. (Guess I will get a pic of that before i continue).  Okay it says Fatal error.  I have also attached a pic from my files showing what .Net Framework is there.

 

I use Windows 7, and as I have said I have had paint.net on here before.

 

Please advise Thanks in advance for your time.

 

Sincerely,

 

Christopher Chance
