Error with accelerator mode of simulink

I am trying to run a rather large SimMechanics model (called Aircraft) in accelerator mode to improve performance. Unfortunately, I get the following error when I run it. Could anyone help me solve this problem? Thanks!

### Building the Accelerator target for model: Aircraft

operable program or batch file.
'nmake' is not recognized as an internal or external command,

The make command returned an error of 9009
'An_error_occurred_during_the_call_to_make' is not recognized as an internal or external command,

### Real-Time Workshop build procedure for model: 'Aircraft' aborted due to an error.

I use MATLAB R2010b and Microsoft Visual C++ 2010 Express.
