Windows cannot access the specified device, path, or file

On some Windows 10 computer, my app (with mysql) does not load. Just saying : “Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item”.

Permissions are R/W on directory and sub directories.
No files are created in the temp directory.

Any idea ?

Make sure you are not using the Windows, program files or those type of directories.

Use the users Public or users Public\Public Documents if you want to ensure write access.

Also can use :\Users<user>\AppData\Local. Setup custom directory for your app and use it that way.

Thank you for your reply. But same error.
There is nothing in the Windows event viewer.

Recommend posting some of your code and how you have the paths to save directories. Really hard to troubleshoot without. Official support will need it for sure.
