Hi,

When we try to install SERP 8.5 210213 build 85360166 on Windows Server 2016, the process stops with such message:
The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2755.
Can anybody help me with this?

Maybe it is important: such behaviour occurs, when we are trying to UPDATE existing installation from version 8.5 200707
