Issue:

The Lai.LicenseManager.exe file was flagged as a false positive in the Malware Database and it triggers antivirus software to quarantine it. This is only affecting the LAI Network Service for ElumTools 2015.11, 2016.8, 2017.4 and older versions. 

Solution:

After the program is installed, if you can make exclusions in your antivirus software, it may be useful to exclude the Lighting Analyst and ElumTools folders: 

C:\ProgramData\Autodesk\Revit\Addins\<version>\!ElumTools.bundle

C:\Users\<username>\AppData\Local\Lighting Analysts\ElumTools

C:\Program Files (x86)\Lighting Analysts\Shared
