Matlab installation problems.

Subject: Matlab installation problems.

Here is a problem of Matlab installation on my computer:

1. My graphics card do not support DirectDraw;

2. Java uses a lot DirectDraw to accelerate speed.

3. So I have to use "-Dsun.java2d.noddraw=true", or otherwise I can see nothing but an empty box.

So, my question is, any way can force matlab installation program not use DirectDraw?

I'm not sure. From your subject line I assume that the fact that Java uses
DirectDraw causes the Installer to be completely blank? If so you should
contact Technical Support for help with this installation question -- they
may know an alternate installation method that doesn't use DirectDraw.

Try adding this directive to a java.opts file - see http://www.mathworks.com/support/solutions/archived/1-1BYDY.html

Note that this directive is used by default in all recent Matlabs, so either
  * the installer is not using it for some reason (in which case you can force it with the java.opts file)
  * or you may be trying to install an old release (e.g. Matlab 7.0),
  * or you may be seeing an altogether unrelated problem that has nothing at all to do with this directive
