I'm following a hyperlink in Excel. It comes up with the warning above, although the linked file is on my computer. I can override the warning and follow the link, but I want to avoid it.
I put the relevant folder into "Trusted Locations" but it made no difference
I was given this solution: open the Registry editor by pressing Windows logo key then pressing R. When the RUN box opens, type regedit there then click OK. Then navigate to this path:Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Security If you do not have the Security key there, that looks like a folder, please create it. If the Security key is there, just add the DWORD (32-bit) Value named DisableHyperlinkWarning then set it to 1.
This worked!
