That means the jbox is not yet recognized with Mazda

 Sounds like another  OE manufacturer that is just trying to toss up hurdles for techs to economically have access to J2534 programming by forcing J2534 device manufactures to jump through hoops and pay big licensing money to be on a list of validated J2534 devices before their program will allow the J2534 device to be used.
  I think that is wrong and Manufacturer should also  have a selection for un-validated  Generic Passthrough devices with a disclaimer and acceptance of risk with no support for  resolving  issues if you proceed to try programming with an unvalidated pass through and it fails.More techs joining NASTF equals more of a voice for pressure on the OEs to make things more accessible  at lower costs.

  the maxisys pro/Elite works fine with mmp, as a matter of fact it works excellent . you have a 64bit os system and that gives issues sometimes. go back to the installation cd and look in a folder name j2534, open it and install it again. if it still don't see it then some computer knowledge is require to go to task manager and update the passthru and select the 64 bit driver, there maybe other ways but for sure your driver is not installed correctly or set up correctly. after the installation is done go to program/maxisys pro/elite, open the software manager and set up your j2534, passthru must be connected and power up. try this or I can help you set it up remotely. good luck

   no problem Dan.  also I just thought of it, check to make sure your firewall is not blocking it, disable it if not sure.

 strange indeed. how about uninstalling it completely and installing from scratch again only this time with the firewall disable, when done open the utility passthru manager and see if it sees the passthru and try to update it. if everything goes ok then open mmp and it will prompt you to set it up. the other thing I will do is to go the programming86 folder, find the maxisys foldel  and copy and paste it to the programming folder. the programming 86 folder is only available to the 64bit os. some software including drivers are only designed to be installed in the programming folder and not the programming86 folder. give that a try and lets see what happens. good luck.
