I have the mspaint.exe from the same version too :P. It complains about registry stuff on launch but other than that it works fine. There's no spray can in the modern paint!
Why does it show registry error?
I copied out mspaint.exe and some resource files as well were needed.
It runs for me without error.
They also added strange hacked on half-support for alpha-transparency in modern MS Paint. Meaning there is an alpha layer, and imported staff may utilize it, but if you need to do anything with that layer, you're basically SOL.
Better to have no alpha-transparency than whatever this is. At least old Paint just turned it white, and you could manipulate the white layer, with this working with the alpha layer is a nightmare.
