How to install the cumulative update files


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 a database with a cumulative update object.


  • Modified the databases or the 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.
    2. Replace the objects in your database that have NOT 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 the table in a cumulative update has the new field and the same table in your database has been modified, use a Merge: Existing<-New or the Merge: New<-Existing options in the Import Worksheet window to import the new fields.

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.


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 Multi-language setting.

  • Use the ClickOnceInstaller (Web Client and Windows Client only)
