P.S. I thought it might be possible to find the 'exe' file in the original download of this driver, but couldn't see one there either.
I am using Firefox browser. HP pavillion a420a
VIA S3G unichrome IGP driver, version 6.14.10.212...
After a lot of searching for an update of this driver, and downloading one that my computer won't recognise, I found this update of the same version, dated 08.
I downloaded it and it came through as a 'zip' file. I have opened the file and its a conglomeration of many files.
I clicked on the 'set-up' file which I thought would install the update but a message came up saying I needed the 'exe' file. I've looked for this particular file, and either I'm blind, !! but I can't see that particular one.
Is there any particular place that the 'zip' files have to be dragged to to get them to download the update.
I've never had an update that has come through as a 'zip' file.
Any advice would be appreciated, thanks.
