Uploading Wordpress Theme

Am trying to install a wordpress theme to the Themes directory in remote server.
Accessing server OK.
Seem to be accessing local server (my own desktop)
Theme has been downloaded and un-zipped.
Using click and drag as per tutorial to drop folder into themes directory.
But folder is placed immediately into Transfer Queue.
System tries to upload but repeatedly fails.
Log created states

It's a permission problem. Please contact your web hosting provider for assistance.
