Navdata center

I am getting the old EPERM operation not permitted, mkdir 'C error when trying to update the ARINC database in MSFS. I have the latest version of all the centre. Have tried many reinstallations.
I have read the old posts on the subject, but nothing works for me. Have confirmed that the app is installed in Users\Appdata\local\programs\navigraph Navdata Centre.
Any ideas
Kev

Hi Kev,

Make sure you have the latest V1.0.12 of Navigraph Navdata Center

Try deleting all files in C:\Users\yourusername\AppData\Local\Temp.

Cheers
Ian
