Hi Vincent,
Thx for your reply.
Can you give me the link for Vaio Care Window 7 64b (and link for requires file to install before Vaio care?) I installed VAIO Care Update version 8.4.4.09186 (Window 8.1 Pro 64b Original driver for this model) but it says I need to install correct version.
Also for Vaio Update, i installed Vaio Update 6.3.1.10120 (Window 8.1 Pro 64b Original driver for this model) but after Sony package manager extracting, the wizard auto-closed, nothing happens.
Regards./.
