Installed the latest 64-bit Windows 10 Pro update (1803). Got a message (don't remember the exact phrasing) that Speccy was removed because it no longer works with this version of Windows.
G’day Bill and welcome.
Try downloding and installing it agin and see if that helps.
YAY! It works!
I noticed that the newly downloaded version is the same i had installed, and which Windows removed (v1.31.732).
Go, figure ...
Bloody computers!
