We are seeing the same problem running 2011b on OpenSuse 11.4
I have not solved the problem yet, but I could narrow it down, that matlab has a problem running unzip.
If you run then following command within matlab in the installation folder, then you will get the same error message as from the installer:
!unzip -qq -d .tmp_patch commusrp_L_v2_1.mwd
We have had similar problems before, it was related to system libraries being newer than the one distributed with matlab.
