I have been able to upgrade to the new version of "VAIO Update" and one of the upgrades was installed, but 2 upgrades are still coming out even if you try to upgrade: -

1.   BlueUpg Graphics Driver (NVIDIA)  -  I get successfully installed but when you check for upgrades it comes back again.

2.   Store App Support Utitily  -   Please wait a while, then try again.

I have tried a few times but still get the same message.

I suppose something will be sorted out by Sony VAIO in due course.
