Hi Dhana1989,
I have checked the Nokia PC Suit`s system requirements. Windows 10 is not included in it. I suspect there may be a compatibility issue.
Here is a link fo reference:

"Compatible with PC Windows 7, Vista, or XP."
To get more help about the mobile device issue, it is recommended to ask for help from our Mobile Device forum.
