anyone ?
Just tried to reinstall it again. Same thing I get the App Centre icon next to the clock bottom right, so left click it, icon appears on taskbar, hover over it can see the App Centre menu in thumbnail then it disappears.
With regards to .NET 4.5 if you try and install it on Windows 8.1 it says its not necessary as it already contains it.
Has this app been tested with Windows 8.1 because if it had you wouldnt need to install .net 4.5 anyway!
