Cant buy new, download or update existing purchased free apps from cloud via iTunes 12.3.0.4? For more than 48 hours, my computer has not been able to download apps - purchase or download updates. I see no error messages, but in the background there are no downloads at all? 

My account seems OK as I can download on my iPad &amp; iPhone with iOS 9.0.2

Why is iTunes 12.3.0.4 on Windows 8.1/PC not allowing me to buy &amp; download free apps or update/ download existing purchases from cloud?
The help article has several options - these are the ones you can check:


Set the date/time on your PC to match an internet time server
Check anti-virus / firewall software on the PC
Sign out of the app store on iTunes and then sign back in


Barring that, you might need to get at the debug or error logs for the App Store - http://www.apple.com/support/itunes/store/ or AppleCare can help. Maybe someone else can edit in where the logs are on a PC.
