I have Acer Aspire V5-571PG with Windows 8 Single Language installed and now I have 2 MAJOR problems. 

1st Problem: 

Yesterday I knew that NVIDIA released a new update (331.82 WHQL) to the Display driver so I downloaded it and tried to install it but I always get the "NVIDIA Installer Failed" message. I searched for a solution and tried everything I found but in vain. 

At last, I tried to uninstall the current driver and try to install the new one. I managed to uninstall the current driver for "Device Manager" but when I tried to install the new one again I got the same message. 

I downloaded the NVIDIA driver from Acer Support website from my laptop's page

But this one also gives me the same message. So, now I ended up without any NVIDIA driver for my card. 

2nd Problem:

I wanted to upgrade my Windows 8 to Windows 8.1 so I followed the instructions here:

http://us.acer.com/ac/en/US/content/update-to-windows81

I uninstalled the Intel Display driver and for the NVIDIA you know from the 1st problem that it is already not there. 

I installed all the pending important updates from Windows Update. 

I opened the store and downloaded the upgrade but each time it reaches the install phase especially at around 70% it stops with error code 0x80070003 I searched the web about this error and tried everything out there but nothing worked. I tried to clear the store cache and it gave me other errors. 

I found some articles about a way around to download Windows 8.1 as ISO and use this to upgrade to avoid the store method errors. But this way required my Win 8 product key. So, I used the one for the windows 8 version installed on my laptop but it told me that this key is only for OEM versions not for retail ones.

So, I would appreciate any help to either of the problems but my most urgent one is the NVIDIA problem.

At this point, your easiest option is probably to restore the system to the default factory load and start over.
