Error using ==> sf Error using ==> construct_error at 109

I have implemented a controller in Simulink that I need to compile to C code to include in my C++ simulations. However whenever i go compile it i get the following error:

Error using ==> sf
Error using ==> construct_error at 109
Failed to create file: C:\Users\Sanchito\Documents\MATLAB\TUM\SeitenBewegung_L1_augmentation\Matlab for Lateral and longitudinal scheduling_UNMATCHED\Matlab for Lateral and longitudinal scheduling_UNMATCHED\slprj\_sfprj\L1_Augmentation_LTV_AmB1B2_xhat_V1\_self\sfun\src\c1_L1_Augmentation_LTV_AmB1B2_xhat_V1.h.

I am using Matlab 2009b to compile this code. Any help would be appreciated. I have tried running Matlab as an administrator but it didnt work.

thanks and regards Sanchito

Does the file already exist? DOes the directory exist? Is it writable ?

Sorry i forgot to mention, I did it with the directory being there and the directory non existing. For both the cases it gave me the same error.
