I try to install and it tells me to open PaintDotNet_x64_143902177.msi but I don't have that file, before that the error was the error 1603, any solution? I don't have the file it asks me to open, every time I try installing it tells me the same thing. Also when I cancel the window that asks me to open that, the paint.net installer says "The installation source for this product is not available. Check that the origin exists and that you have access to it." and the error code when this appears is 1612.
