Laura,

I found the issue that Michael submitted back in 2012 here: https://www.labkey.org/announcements/home/Developer/Forum/thread.view?entityId=1dba004f-b262-102f-ac60-987439a648f8&_docid=thread%3A1dba004f-b262-102f-ac60-987439a648f8

According to the information from back then, it looks like there is a problem with authentication since it's a 401 error message.

Can you verify if your netrc file is configured correctly? (See documentation: https://www.labkey.org/wiki/home/Documentation/page.view?name=netrc)

Also, the specific problem that Michael brought up was isolated to where the netrc file was located in, so I would recommend verifying whether the file has to live on \home\Documents\R\win-library vs \home\R\win-library on your Windows machine.

Regards,

Jon
