Hello Richard,
I am so sorry for all this trouble! Well, it is just an optional driver update and the officials Canon drivers install and work just fine without any error messages. I just want to solve this in case it is a symptom of a system corruption.
Anyways, I searched the Windows Update catalog but could not find the exact match for this driver:
Microsoft Update Catalog
The problem is it shows up as "Canon - Printers - Canon MX430 series FAX" with a size of 14,0 MB, description of "Canon Printers software update released in June, 2012", and published on 21.12.2012 in Windows Update. There is only one 14 MB Canon driver for this printer released in June, 2012 - however, its description is quite different "Canon Enterprise WSD Multi-Function Printer, Other hardware software update released in June, 2012".
One thing that caught my attention is that the catalog shows up 2 different fax drivers for this particular printer with the same version number, list of supported languages and release date:
Canon - Printers - Canon MX430 series FAX
Son Değiştirme: 28.06.2012
Boyut: 28,0 MB
Microsoft Update Catalog
Canon - Printers - Canon MX430 series FAX
Son Değiştirme: 28.06.2012
Boyut: 27,4 MB
Microsoft Update Catalog
I checked both and the only difference I could spot was the different size. Also a little translation for you - "Son değiştirme: last update", "boyut: size" - I believe those are fairly obvious though
A new update showed up in Windows Update today - this time it is for my graphics card. I updated my AMD Radeon HD 7850 with the latest Catalyst 13.1 released on Jan 17, 2013. However, Windows Update thinks that there is an important driver update released in September, 2012 and published on 2.11.2012 for my graphics card! I have begun to wonder if I will need to hide all these driver updates manually. Is it possible that there is something wrong with the Windows Update driver update mechanism and it cannot always suggest the right driver update due to versioning system of some vendors? Maybe the database Microsoft is using is not always up-to-date for every device driver and that's why it offers to install outdated drivers. Or maybe there is something seriously wrong with my system and this prevents Microsoft Update to work properly :/
Thank you for your time!
