HELP PLEASE ... How to uninstall the DSP builder

Hi All,

I have installed my Altera DSP Builder on Matlab 2007... But i noticed that it is not compatible .. Matlab 2007 doesn't support the demo...

Now i have installed Matlab 2008 and i would like to uninstall pre-installed DSP builder then install the Altera DSP Builder again...

but when in the middle of installing the DSP builder, i got error message that

"Unable to locate uninstaller" ...

Tilll now i can't uninstall the Builder...

What should i do??

Many Thanks
