Although the topic about pkinfo was addressed in the question What is *.pkinfo file? on this occasion it does not matter about "what is a pkinfo file" but rather if there is any solution to the problem of the "error 403" message after following the instructions on the support page from esri https://support.esri.com/en/technical-article/000011109
I tried to open a item.pkinfo file without ArcMap, following the steps detailed in Esri support page, Meaning :
Open the item.pkinfo file with notepad and copy the URL between tags
When I go to the specified URL, I get this message:
"You do not have permissions to access this resource or perform this operation. error 403"
Does anybody know how to solve this issue?
