MATLAB R14 on WIndows 7 X64 ???

[Freddy Huizinga]

I'm having problems installing Release 14 (Service Pack 1) on my new computer (Windows 7 Ultimate edition, X64).

After installation, MATLAB won't start. I have tried the following, but witjout success:
* Defining MATLAB_JAVA environment variable to the installed Java version
* Define MATLAB to run in compatibility mode (Windows XP, SP3).

Any ideas how to solve my problem?

Hi Freddie,
same for me! Except that Release 14 even couldn't be installed.
Cheers,

Greetings! And it gets even worse... I went to the trouble and cost of upgrading to Windows 7 Professional X64. I then downloaded the programs necessary to run XP Mode in a Virtual PC. This took time but all went well... and my desktop looked for all the world like XP. I was apparently able to install R14 without problem. However, when I went to run it the first time... I got a "License Manager Error -103". Reading up on that eroor... I looks like MATLAB either doesn't like the Virtual PC or detects "multiple users"... and I can't log out of Windows 7... as that turns off the Virtual PC. Needless to say... I am not a happy camper!

Best wishes

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.

I need some help. I did exactly what is suggested; however I still have a problem. As long as I launch MATLAB the desktop pops up for a second but it crashes right away. This happened too right after instalation using the Classic theme and before pasting the java into ...\sys\java\jre\win32.

I can't get MATLAB to launch, I just installed it in Windows 7. It worked very well in Windows Vista.

Thanks

David,

Your java fix worked, however I am having the same problem as Hugo. Matlab opens for about 2-3seconds and then closes. No error message, just closes. Do you know what might be wrong?

Cheers,

Craig
