This is an old question but I just ran into this problem myself and wanted to add what I've just discovered, in case it's helpful to anyone else.

If you have UAC turned off but are not running with elevated permissions, and try to write to restricted files (e.g. the "Program Files" folder) you'll get the "could not find a part of the path" error, instead of the (correct) access denied error.

To eliminate the problem, run with elevated permissions as in this solution: https://stackoverflow.com/a/1885543/3838199
