ORIGAM 2018.1.44 - XSLT validation error

After installing ORIGAM 2018.1.44 by Setup.exe and running dektop Architekt I get Could not load file or assembly ‘MoreLinq, Version=2.10.21623.0, Culture=neutral, PublicKeyToken=384d532d7e88985d’ or one of its dependencies. The system cannot find the file specified.
on screen and in output there is a message “Could not load file or assembly ‘MoreLinq, Version=2.10.21623.0, Culture=neutral, PublicKeyToken=384d532d7e88985d’ or one of its dependencies. The system cannot find the file specified.”

Any idea why is that?

It was because the instalation Setup process is missing MoreLinq.dll in all web application, dekstop architekt and desktop client. I took MoreLinq.dll from dekstop architekt 2018.2.60 distribution, restarted the software and everyhting is OK.

Fixed in build 2018.1.45, MoreLinq.dll is part of the distribution now.
