NAgent upgrade failure due to mismatch between .msi packages [KSC for Windows]


Problem
Network agent upgrade fails. Network Agent installation from an .msi package different from the new .msi package is the root cause. See the below logs:
KLNAG_INS_MSI: CheckInstalledMsiName: installed name 'KasperskyNetworkAgent', installed ext '.msi' 
MSI_UTILS: CAGetProperty(OriginalDatabase) called... 
KLNAG_INS_MSI: CheckInstalledMsiName: installing name 'Kaspersky Network Agent', installing ext '.msi' 
KLNAG_INS_MSI: CheckInstalledMsiName: names are NOT equal 

Solution

  1. Copy the installation package of new NA version from the shared folder and place it on Desktop for example.
  2. Change the name of the .msi package related to the new version of NA to match the name of the installed .msi package.
