Upgrade to 5001 from build 4112 Not Compatable

When I try and run the upgrade from build 4112 to 5001 I get a message that states the PPM is not compatable for this product?

I was on build 4102 and used updatemanager to go to build 4112 and then tried the same procedure to go to build 5001 as it is explained below? Can anyone help?
