After Windows patching of the UIM Primary hub, the data_engine probe (and probes that have dependencies on it) do not start. The data_engine log shows only max restart error messages.
In attempting to start the data_engine probe from the commandline, popup stating that there are missing files (vcruntime140_1.dll and msvcp140.dll).
In looking for these missing files, they are not found in the Windows\System32 folder.
Release : 20.3
Component : UIM - DATA_ENGINE 20.31
A corruption of the Visual Studio C++ Redistributables causes the missing files.
Microsoft has identified issues with these packages. This was posted in their answers forums:
