I have installed the last Microsoft update, as you advise, but the issue still presents.
BTW, I have news, about the trouble, I called "Roxio Creator NXT Pro 3 and the mistery of Windows 10".
Upgrading from Windows8.1 to Windows10, the system saved all the programs stored in my PC and moved them to a specific folder named 'Windows.old', which contains the following subfolders; 'Program Files' and 'Program Files (x86)'. In the latter, the following subfolders are placed; 'Roxio' and 'Roxio Creator NXT Pro 3' containing the program 'RoxioCentralFx.exe' used to start the GUI of 'Roxio Creator NXT Pro 3' (see the attached image).
If I launch the task 'RoxioCentralFx.exe' from the folder placed in 'E:\Windows.old\Program Files (x86)\Roxio Creator NXT Pro 3\Roxio Central\', the GUI of 'Roxio Creator NXT Pro 3' opens properly. On the contrary, if I launch it from 'C:\Program Files (x86)\Roxio Creator NXT Pro 3\Roxio Central\' a program error occurs and is displayed.
Furthermore, if the program 'Roxio Creator NXT Pro 3' is launched using a second account in my PC, the program runs properly.
Could you perhaps explain me why? Same "car", but different "drivers"...!!!!
Up to now, a workaround has been available by means of creating a link named 'Roxio Creator NXT Pro 3 - link(E)' which launches the 'RoxioCentralFx.exe' program, placed in the folder 'E:\Windows.old\Program Files (x86)\Roxio Creator NXT Pro 3\Roxio Central\'.
Thanking you in advance for your help in this matter, I send my best regards.
