I just upgraded the 2019 program only to find that now it won't start.

The icon has disappeared from the desktop.  When I try to launch the

w19tax program from the File Explorer, I get this message in a pop-up window:

"Windows cannot access the specified device, path, or file.  You may not have

the appropriate permissions to access the item."

I'm running Windows 8.1 Pro, 64-bit.
