I have searched the site for 3 days and finally found a post titled; "IAK user login and MAX configuration" on 4/21/2009 that asked about the same issue I am having. I am wondering if there is anything new on this topic as I need a solution.
I have installed an application and the NI FP driver suite ver 6.0.11 . I run NI MAX and open my .IAK file, which is located in a common folder/directory along with my application executable. At first I used to hit the "Save" selection but have found since that it makes no difference so for now I do not hit "Save" but simply close MAX. This process is registering the location of my .IAK file somehow, because after this my application runs and communicates with my I/O fine.
The problem comes when I have new station operators log in to the PC that controls my testing operation; the application, which auto starts because it's in the "All Users" startup folder, can't communicate with the I/O.
Running MAX and opening the .IAK file under each new user login then immediately closing MAX fixes the problem and everything is fine, and this process only needs to happen the first time a new user logs in to the PC. The above mentioned post indicates that this is normal behavior.
The problem is that some of my operators are doing good to find the power button and turn everything on in the morning. The application has no "Exit" facility so "Task Manager" must be used to stop it. Their login information is kept on a post-it in their wallet, and to ask them to open MAX and register the configuration is just too much for them to do - being unfamiliar with the operation to begin with.
Can anyone explain to me how to fix this problem or refer me to a posted solution?
Thanks
