HydraLIST appears to not open, but appears on task bar.

After attempting to download the Latest Toolbox, a warning appears saying the file cannot be opened. 
Tells user to delete toolbox .rvt file and try again, but that does not work. 

Double-clicking your HydraCALC icon makes nothing happen.  You do not see HydraCALC open onscreen nor on your taskbar.  HydraCALC does not open other than in the task manager.

If you open your task manager and see the app "Hyd_prog.exe" open but not on your taskbar, then the application is stuck in purgatory.

Another possibility may be that it's on the taskbar but not on your screen.  That means it's open but offscreen. 

See this HydraCARD to fix that issue;  HydraCARD 565 only AFTER you've checked on the solution below.
