Problem running COMSOL 4.0a with MATLAB

Hi all,

having studied the manual, I can't get the LiveLink for MATLAB functioning. I use Windows and MATLAB R2010a. At my university the preferred way is to first start a COMSOL server and then start MATLAB and run the mphstart function. The mli-path is added to the MATLAB directory. COMSOL is listening to port 2036, but when running mphstart gives the following error

??? Java exception occurred:
java.lang.RuntimeException: Not possible to determine the installation path 'cs.root'.

Error in ==> c:\Program Files\COMSOL40a\mli\mphstart.p>mphstart at 68

It seems like there are some incorrect folders somewhere. I've checked the ini-files and they seem ok. Anyone have any suggestion what to do?
