I have an ASUS X510UQ (circa 2017) and wanted to share what finally worked for me. I installed the generic MS HD drivers instead of Conexant as recommended, which stayed in place for at least a week without any blocking. I wasn't offered the update to 2004, though, until I actually pulled two .dll files in the offending range (uci64a96.dll through uci64a231.dll -- for me, it was UCI64A134.dll & UCI64A231.dll) out of the System32 folder. The update appeared within 24 hours and installed no problem. Conexant drivers were reinstalled automatically after install.
I do now have an issue, however, where if I manually check for updates, I receive the error "A current driver on your PC may be better than the driver we're trying to install. We'll keep trying to install." regarding some Intel driver.
What is the Intel driver that you are trying to update?
How are you "Manually" checking update to the said intel drivers; through "Optional Windows Update" or from within "Device manager"?
