problem with dsp builder & Quartus II Path

[Altera_Forum]

Hi everyone, 

 I have many versions of quartus II because I need them all; but Iwant to use dsp builder with quartus v8.0; It doesn't work; I verified the Quartus II Path by typing this command: !echo %QUARTUS_ROOTDIR% and I get this: >> !echo %QUARTUS_ROOTDIR% %QUARTUS_ROOTDIR%   I verified that QUARTUS_ROOTDIR point to the correct version of quartus in the Environment Variables. Please help:confused:

To make sure QUARTUS_ROOTDIR is set correctly, right-click on My Computer and select properties. Then click on the Advanced tab and select Environment Variables. Now check that QUARTUS_ROOTDIR is there (adding it if it's not to System Variables although I think user variables will work as well). Click OK. 

 now restart matlab and try again. I think !echo %QUARTUS_ROOTDIR% will work, but FYI the MATLAB way to do it is "getenv QUARTUS_ROOTDIR".
