Every time I tried to install paintdotnet the program wanted to install dotNET 4.5.2 even though I have it already. It always failed, so I tried to repair it using files on my computer and got past that problem but then it threw this exception (see attachment). Please tell me how to fix this.

Thanks for your reply. My poor explanation should have indicated that what I tried, and succeeded, to repair was the .Net installation. The exception came after that.

The exception says that it can't load IReadOnlyCollection, which is a core interface defined by .NET 4.5: https://msdn.microsoft.com/en-us/library/hh881542(v=vs.110).aspx

 

If that can't be found, it indicates something is broken with your .NET installation. You say you already tried repairing it, but clearly something is still broken with .NET itself.

That's good news :)

 

I recommend installing .NET 4.6. The next update to Paint.NET will be using .NET 4.6 so you'll save some time if you let that install while you're doing something else (as opposed to having to wait for it when the next Paint.NET update arrives).

 

It's probably not the version of .NET that matters here. Going to a different version probably just forced the installer to be more thorough.
