Cannot write file

I'm completely new in Qt,couple days ago just installed the program,and from the beginning had error messages suddenly appeared over and over in random time(but every time when program just starts 5-6 times).

The text of it like this: Cannot write file C:\Users\Admin\AppData\Roaming\QtCreator\qtproject\qtversion.xml.

This stuff starts freak me out completely just in the second day of studying Qt,google did'nt help,have no idea what should i do.Disk 100% not full,65 gb available on disc C,Have windows 10 Education and qt as i understand 5.10.1,but for some reason there is no such thing in your "Affects Version/s".
