Thread Subject: build GUI to exe

Using Windows Vista Home premium SP1 and matlab R2009b.
I'm using the default LCC to compile. The files are as simple as A.fig and A.m.
I type command "deploytool", and added A.m, then click "build".
After compilation, I double click the exe file in the "distrib" folder.
Here is the error:
********************Unable to locate Component*************************
The application has failed to start because mclmcrrt711.dll was not found. Re-installing the application may fix this problem.
********************************************************************

How come? Thanks.
