It sucks that the VC++2012 dependency is not checked and flagged by the installer and its sucks even more that there is zero mention of the VC++2012 requirement on the KB article for CU11.
So many like me will end up with broken servers giving cryptic messages and have to search the internet to find the cause.
- @TDR - This was called out in the original blog post. It was even bolded to call attention to it. Your assumption that the installer does not check is not accurate. The installer does check but when it runs the first time the binaries are installed from the previous cumulative update so the check passes. The fact that when you run setup a second time and the pre-req shows is proof that the installer checks and that the versions previously installed by setup have now been removed and replaced by a pre-req check.
- So what happened to me was my Edge server install crashed out half way through with an error telling me to reboot. Not unusual with CU updates - they sometimes fail and you have to rerun them from where they left off.
However due to the VC++2012 issue - when I tried to rerun the CU, the installer just stops. No on screen error, except a cryptic message in the setup logs about some specific DLL dependencies. I had to spend quite some time and the System Internals tools to work out it was looking for VC++2012. I found this article subsequently.
So if that information is needed here, I would have thought it's pretty obviously needed on the KB article. Not every person tasked with installing this is going to think to check a specific blog. Installing CUs is often frustrating enough as it is - you need to update the KB please.
AND the CU installer really should detect and display a user friendly error message for such a dependency error without just dying.
