Open of directory failed

A -3016 error is caused by a system directory on the machine being mis-set, pointing to a non-existent directory, having permissions problems, or something similar.

Solution

Check that the directory in question exists, and the user has appropriate permissions.

The problem may be related to one of these two special directories on Windows:

CSIDL_COMMON_APPDATA CSIDL_COMMON_DOCUMENTS

The library tries to find the path to each of these directories and the Windows function call (SHGetFolderPath) is failing for one of them.

In some cases, one may wish to ignore use of the CIDSL_COMMON_DOCUMENTS directory. The library will not collect information from this directory if the "Remove Dir Check" checkbox is ticked when the library is created on the Nalpeiron site.

If you are unfamiliar with the CSIDL method of designating directories, here is a link from Microsoft that may help: https://docs.microsoft.com/en-us/windows/desktop/shell/csidl

To find the location of special folders, we found this link in a search: https://www.nirsoft.net/articles/find_special_folder_location.html

We have no connection to that website and so cannot vouch for the utility.
