Hi Martin, thanks for the reply.  Oddly enough, it worked today when I tried again (running it from the command prompt).  I can only imagine there was something odd with the laptop, but I don't know what it was.  Thanks again!
                
            
        
    
    
        
        
            
            
                Can you please start the installer with /log=c:\some\path\setup.log command-line parameter and post the log here?
                
            
        
    
    
        
        
            
            
                I'm using Windows 10 Enterprise (ver 1809) and attempting to load WinSCP 5.17.5.  I currently have WinSCP 5.15.9 loading and working properly.  When I double-click the WinSCP-5.17.5-Setup.exe file, it states "You must be logged in as an Administrator when installing this program." and aborts immediately.  I'm 100% sure I'm logged in as an Administrator on the laptop and I've tried deleting and downloading the setup file a couple of times, but continue to have the same issue.  I'm starting Windows Explorer by opening a CMD prompt (Run as Administrator) and then typing "explorer.exe".  Unsure how to get past this issue?  Thanks
