If it's Win 7 or Visat, try starting MATLAB in admin mode. Right click on MATLAB icon and select run as admin

Windows 32 bit versus 64 bit?

Is the same version of MATLAB being used in both systems?

Are you using the legacy interface or the session based interface? The DAQ 6221 appears to be too old for the session-based interface.

the windows was the same...

I just had this problem last week. You cannot use any NI DAQs except Compact DAQs with the 64-bit version. You have to install the 32 bit verseion of MATLAB, and run it as an administrator.

The prerelease of R2011b Data Acquisition Toolbox supports many non-compactDAQ devices with Session-based interface.

If you have a valid MATLAB license, you can download the R2011b prerelease from here

After installation, try

daq.getDevices

to get a list of all the devices.
