With Protel it isn't possible make a layout with embedded resistors, that means you can design PADs to a resistor not only to top or bottom layer for example for printed resistors on a ceramic substrate . I took a look on Pulsonix but there are some missing features. The website for Altium-Designer is telling nothing about this. Is there a layout software that is able to design embedded resistors?

Pulsonix has support for embedded components. I don't actually use it, but it worked OK when I tried it some time ago. What are the missing features?

What's an embedded resistor?
It is possible to use Protel for this purpose. Ink areas are merely assigned to internal layers and a composite photoplot is made of all layers which are then separated for each screen. The resistors that you use in hybrids are then a function of the layer and thus the ink resistivity, and the pad shape through the length to width ratio. The resistors are then usually trimmed to value with a laser trimmer.

A thick-film resistor that is manufactured on an inner copper layer.

Pulsonix has embedded components but else it's relativly primitive.

You can print resistors. There have to be 2 pads and a machine prints a resistor pasta between the pads.
Could you elaborate a little more? I'd grant that Pulsonix isn't the fanciest package out there -- something like PADS is probably a better choice if you have really good layout guys (uncommon) and truly challenging boards (also uncommon) -- but Pulsonix is definitely a solid step above what I'd consider "primitive" -- stuff like the free ExpressPCB package, possibly Marra's software (which I haven't actually tried, this is based strictly on reading the documentation on his web site), etc. (Also note that I'm not making any value judgment here -- something like Express PCB at "primitive features over zero cost" is going to be much more valuable for some people than something like PADS at "features out the wazoo but over huge cost.")
Primitive compared to what?

Sorry, you are right. I confused Pulsonix with Cadstar. It seems that Cadstar doesn't offer rounded corners at tracks.
