Having issue installing kb500556 update

Yes, there are several threads where that was reported.

This is the problem where people essentially hack the O/S - do something the designers don't expect, plan for or test for.

It would be unreasonable to expect updates to be successfully applied in every case where something delivered with the O/S has been removed or changed.

The difficulty for respondents here is not knowing what's been done to the O/S - its history- and then having to spend time trying to analyse log files, which are not very helpful or clear.

At some point the response becomes simple- rather than spend time (again), take the expeditious approach of recommending an in-place upgrade repair install, which is likely to give the fastest and most routine fix.

Makes perfect sense, as I've been that route in the past.

Since there were numerous problems on HP machines last year, and a lot of trouble updating to later W10 versions because of Conexant drivers, I now briefly note or document any changes I make to the O/S, along with other key applications, hardware alterations, important settings and so forth. This gives me a reasonable route back to determining possible causes of errors or malfunctions.

It shouldn't really be necessary, but many of the log files are as you describe, and thus of little use.
