MATLAB: Make error in compiling simulink 3d simulink file

make errorsimulinksimulink3dstateflow

[EDIT: 20110731 17:37 – reformat – WDR]
Hello all,
 I am working on simulink for 3d animation but I receive this error when I compile the file.This error was not shown sometime when I previously worked with it.So can anyone suggest me what is the supposed cause of the error
The error comes under the heading 'Make error' with this dialogue The dialogue is as follows:

The problem here is only with the last part all other things are fine (as it seems) with this dialogue.
 Any suggestions will be very helpful for me as my whole project work is halted because of this.

Best Answer

I second Walter's theory about the writability of the directory. An easy way to check this would be to run MATLAB as administrator and see if the problem occurs.
