How to install a Microsoft Dynamics NAV 2018 cumulative update

This article describes how to install a cumulative update for Microsoft Dynamics NAV 2018. You have to recompile all objects after you install a cumulative update.

A cumulative update is a cumulative set of files that includes all hotfixes and regulatory features that have been released for Microsoft Dynamics NAV 2018.

A cumulative update includes files that are separated into the following folders:

• APPLICATION
• DVD

See Upgrading the Data to Microsoft Dynamics NAV 2018 for details.

APPLICATION

The APPLICATION folder includes the following files:

• AccumulatedChangeLog.<Locale>.<Build No.>.txt
• Changelog.<Locale>.<Build No.>.txt
• CUObjects.<Locale>.<Build No.>.fob
• Objects.<Locale>.Objects.<Locale>.<Build No.>.txt

To install the application files, follow these steps:

• Unmodified databases:
  1. Import the CUObjects.<Locale>.<Build No.>.fob file into an unmodified Microsoft Dynamics NAV 2018 database.
  2. Replace the existing objects in the database with the cumulative update objects.

  For more information, see How to: Import Objects.

• Modified databases or local databases for which local cumulative updates are not released:

  1. Import the CUObjects.<Locale>.<Build No.>.fob file into the Import Worksheet window in your modified database.

     For more information, see Import Worksheet.

  2. Replace the objects in your database that have NOT been modified.
  3. Use the CUObjects.<Locale>.<Build No.>.txt file to compare and merge the cumulative update objects with the objects in your database that have been modified.

  Or, you may use the Changelog.<Locale>.<Build No.>.txt file to manually apply the changes to the objects in your database.

  Note If a table in the cumulative update has a new field and the same table in your database has been modified, use the Merge: Existing<-New or the Merge: New<-Existing options in the Import Worksheet window to import the new fields. For more information, see Options for Merging Objects.

Note about Regulatory Features If a license update is required for a regulatory feature, customers can download an updated license from CustomerSource and partners can download their customers' updated license from VOICE. For more information, see the following How To articles:

PLATFORM

The following components are defining the Microsoft Dynamics NAV Platform:

• Microsoft Dynamics NAV Web Client
• Microsoft Dynamics NAV Windows Client
• Microsoft Dynamics NAV Service Tier

The Microsoft Dynamics NAV platform can be installed by the following methods:

• Use the installation program
  • Un-install current client or server
  • Open the DVD folder and run the setup.exe
  • Connect to the database
  Note This is a recommended method because different installations may have different strategies. For example, stx/etx file updates may not be included in a localized or Multilanguage setting.
• Use the ClickOnceInstaller (Web Client and Windows Client only)
  • For more information, see Deploying Microsoft Dynamics NAV Using ClickOnce.
