Micromega MyDac and Windows XP

Perhaps you need to disable your virus protection and firewall?

During installation of the driver, you are asked to disconnect and reconnect the DAC. This is where the program seems to fail.

When you reached that point, before disconnecting the DAC did you check to see if there was a "safely remove hardware" icon in the systray area (at the lower right of the screen), and if so, if an entry corresponding to the DAC appeared when you clicked on that icon? If there was, that entry should have been clicked before disconnecting the DAC.

Also, the instructions here refer to connecting the DAC when prompted during the installation process, not to disconnecting it and then reconnecting it. Sometimes driver software has to be installed before Windows "sees" the associated hardware. Try uninstalling the DAC in Device Manager, then shutting down the computer, rebooting with the DAC disconnected, then re-doing the driver installation with the DAC only being connected after the prompt to connect it appears.

Thanks for the suggestions. I have tried most but will start again from scratch. BTW, the same driver install issue occurs with Windows 7 on my laptop. Will report back.

Uninstall and reinstall fails. The actual dialogue box within the installer says to 'remove, reinstall and turn on the device you wish to install.' Anyway, I tried it both ways to no avail. Next step is talking to the U.S. Distributor.

Another thought: Are the USB ports on your older XP computer USB 2.0? If not, and they are USB 1.1, that would probably explain the problem with that computer. If you are not sure, let us know the make and model of the computer, and/or the approximate year it was purchased.

And are you using a USB 2.0 compatible cable? If by any chance you are using a cable dating back to the days of USB 1.1, that would probably explain the problems installing to your Windows 7 computer as well.

Hope that helps. Regards,
