I discovered that I could not perform the hotfix routine and point it to a UNC path longer than a root share. For example, I tried \\servername\clients\clientname\LeM\hotfixunzipped and that failed, so I tried it repeatedly and moved the hotfixunzipped folder up 1 parent folder at a time and only when it was shared from \\servername\c$\hotfixunzipped did it finally see the hotfix and install it. All prior attempts gave the typical bad credentials error. I had also tried the hotfix from a unc path I was connected to over a Cisco Anyconnect VPN session, and no folder path worked across the vpn, even when using \\serverIPaddress\c$\hotfixunzipped. I had to move it to my local laptop and perform the tests above to get it to eventually install successfully.
Thank you!!
