Upgrade Error for In-Place Install to 5.17.8 on Windows Server 2016

I am running WinSCP version 5.17.7 (Build 10640) on Windows Server 2016. I get a pop up window requesting an update to 5.17.8. I've attempted this a couple times and am getting this error: "Cannot upgrade WinSCP DeleteFile failed; code 5".

The only file listed is:

D:\Program Files (x86)\WinSCP\WinSCP.exe

How can I fix this and get my version of WinSCP to the latest version?

Thanks!

What you start the installer, do you get the UAC (Administrator privileges) prompt?

Can you post the installer log file?
(use /log command-line switch – see https://winscp.net/eng/docs/installation#automating).

This morning I turned on logging and was able to get this to self-install. Sorry for the alarm and I appreciate the quick response. Like an old Dodge, this "fixed itself".

Thank you for such a great product.
