I don't know for certain if I have figured out this problem, but I think I may have.? ? Several times I've had problems compiling my own or other code (most recently some examples in a christmas arduino kit for a present....) where the linker says it is
"unable to ...."? do something to some file due to it already in existence....suggesting a "permissions" problem.
A relative showed me how to use the File Explorer inWindows,?go to the .ino file and RIGHT-click,
go to PROPERTIES
go to SECURITY
and then adjust the PERMISSIONS so that I and other authenticated users) had "full control"
and then the example I was working on compiled fine.
Wow....my only previous real experience with this was with raspberry linux....so seeing how to do this with the graphical user interface was a learning moment.??
