I had a similar problem which I have just fixed. I am using R14 on Windows 7 Professional on a 64 bit quad-core Intel i7. In my case, when I started MatLab I got the splash screen, then very briefly an error window full of text which appeared and disappeared in a fraction of a second. Looking in the Temp folder, I found both a Matlab crash dump AND a java crash dump. The problem, it turns out, was that the version of java embedded with R14 does not work on Windows 7. So, here's the fix.

1) Find the 32 bit java installed on your machine. (Mine is C:\Program Files (x86)\Java)
2) Copy the JRExxxxx folder that you find there into the java folder under <MatLab>\sys\java\jre\win32. In my case, this meant copying
C:\Program Files (x86)\Java\jre6
to
C:\Program Files (x86)\MATLAB704\sys\java\jre\win32

3) In the destination folder you will find a jre.cfg file. Edit it. It contains the text '1.5.0'. Replace this with whatever follows the 'jre' folder name you just copied. In my case, this is just the digit 6

Voila!

I haven't run lots of MatLab stuff yet to see if everything is working. There are probably some Java packages in the jre1.5.0 folder that will need to be copied to the new jre6 folder. But note that this fix not only allows MatLab to run, but if fixes the "my buttons don't appear" UI problems that others have reported running R14.

Cheers!
