I've been trying to upload the NVIDIA Guard Service from VAIO Update service for a couple of weeks now with no success. The update is downloaded but won't install. Every time I restart after downloading it comes up as a failed installation. This was after about a week of trying to upload the new VAIO Care version (which eventually worked).

Error Code in the installation history is 0xA0011000(5).

I also tried to upload directly from the website. That suggests installation is complete but when I run VAIO Update it tells me the NVIDIA Guard Service update is available to download. I click Update and I am into the cycle of "failed Installation" again.

Any thoughts?

I have a VAIO Laptop VPCF12S1E.
