Hi @Erik_Rose,
This is more of a Windows file permissions question than an OJS question, and I’m not particularly familiar with Windows’ model. I’d suggest trying with a quick test script:
<?php
echo is_writable('/path/to/files-path')?'writable':'not writable';
Executing that script will tell you whether PHP has permission to write to the specified path.
