There are 3 yellow-icon warnings in the event viewer application group, with this explanation: "Profile notification of event Load for component {B31118B2-1F49-48E5-B6F5-BC21CAEC56FB} failed, error code is See Tracelogging for error details."  Not particularly helpful, but the entry does point to SYSTEM as the user.
In the SYSTEM group, there are errors at a comparable (but not identical) time-stamp for "Event 10016, Distributed DCOM"  which provide this general description:
"The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 
{2593F8B9-4EAF-457C-B68A-50F6B8EA6B54}
 and APPID 
{15C20B67-12E7-4BB6-92BB-7AFF07997402}
 to the user RIVENDELL2\James Vance SID (S-1-5-21-3774824159-2135294730-2250967024-1002) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

------------------------------------
Insofar as an installation log for v4.5.2, I can't find one -- it's occurred to me they may not be created when in safe mode, but don't know.  Under the setup group of logs, the last of those dates from Patch Tuesday a few days ago.
