I've finally managed to better understand the issue and here is a step-by-step guide.
First things first: the problem is related to file security and your user login access rights. When the non volatile memory file is first created as a normal user, it will be fine. However when the non volatile memory file is first created when running as-admin, it won't have your user account access rights therefore it won't be accessible by the trainer when you run as a normal user.
1) locate the GTN 750 #1 non volatile memory file. It should be:
2) right click the sys_nandi file then select Properties > Security
Your user account shouldn't be there if the file was first created when running as-admin:
This is what is expected if the file was first created normally:
this tells your [username] login has all the listed access rights (Allow column). The most important ones are: Read, Write and Read & Execute.
3) Click the "Edit" button to change the access rights
4) Click the "Add..." button to add your user account
The "Select Users Or Group" window opens. Type your user account/login name in the "Enter the object names to select" area, then click the "Check Names" button to the right to validate, then click OK.
The Permissions panel should show something like this:
5) Click the "Read & execute", "Read", and "Write" boxes in the "Allow" column then click "Apply" then "OK"
The sys_nandi file should now have access rights both for your user account when running normally and when running as-admin.
add your user accounts read and write access rights
