It took 2 days of searching to solve this problem. There are many threads out there but no real solution. The most peoples are just talking about the theoretical way but not about the practical.
Here is the problem:
When drawing shapes or lines out of the code (without using the toolbox) the application probably wont work on other computers without further attention to the references. An error will show up "filenotfoundexception" on computers which havnt got visual studio. The point is visual studio is using PowerPacks which isnt showing up in the reference-list.
Searching for the missing dll around the web is pretty useless. I really tried hard without success.
Ill answer this question myself just for documenting this issue. I hope this isnt against the rules. Its just about: So many people out there got this problem and no one got a solution.
This question will get closed in 2 days!
