Problems with creating a CUDA dll

Hi, i am trying to create a CUDA dll, and call the CUDA functions from a Windows Form application. However, when i run the program, dll is created fine but when i combine it with other project - the GUI project - and run it, i get the error:

“Cannot run the program because cudart32_41_28.dll was not found”.

However, i have looked and in my \bin folder i do have this dll so its very strange. What can i do to solve this issue?

Thanks for any help!!

pls mail me solution if this is possible
