Control Add-in Error When Accessing Charts in Microsoft Dynamics NAV

Summary

When opening Microsoft Dynamics NAV, users may encounter the following error messages on the Role Center homepage or when attempting to open charts (e.g., from the Chart of Accounts):

1. Error on Role Center Homepage:
   “Could not locate the control add-in library for ‘Microsoft.Dynamics.Nav.Client.BusinessChart’.”

2. Error on Chart of Accounts / G/L Actual Budget Chart:
   “The control add-in on control Chart on page G/L Acct. Actual Budget Chart has not been instantiated. Page Budgets Commitments Balances must close.”

These errors occur because the Business Chart Control Add-in required to render the charts is missing, not properly installed, or not enabled on the NAV client.

Resolution

To resolve the Control Add-in error in NAV:

1. Confirm Add-in Installation

   • Verify that the Business Chart Control Add-in (Microsoft.Dynamics.Nav.Client.BusinessChart) is installed on the client machine.

   • This add-in is typically included in the NAV RTC (Role Tailored Client) installation. If missing, re-run the NAV client installer and ensure the Business Chart add-in option is selected.

2. Check Add-in Deployment in NAV

   • Go to Departments > Administration > IT Administration > General > Control Add-ins.

   • Verify that the Microsoft.Dynamics.Nav.Client.BusinessChart add-in is listed.

   • If it is missing, it needs to be re-deployed from the installation package or imported manually.

   • You’ll need to re-import it from the NAV installation media or ensure the add-in DLL exists in the client’s Add-ins folder (usually under:

     C:\Program Files (x86)\Microsoft Dynamics NAV\<version>\RoleTailored Client\Add-ins\

3. Clear Client Cache

   • Sometimes cached Role Center data prevents the add-in from loading correctly.

   • Close NAV and clear the client cache (usually located in %localappdata%\Microsoft\Microsoft Dynamics NAV).

   • Restart the NAV client.

4. Clear Add-ins Temp Folder (Recommended Fix)

   • Close all NAV Clients.

   • Navigate to:

     %TEMP%\Microsoft Dynamics NAV\Add-Ins\
     

   • Delete all contents from that directory.

   • Reopen NAV and try again.

Additional Information

• These errors are cosmetic if you do not rely on NAV charts. Core NAV functionality (transactions, posting, reporting) is not affected.

• If your organization requires chart functionality, ensure the Business Chart Control Add-in is correctly installed and registered.

• In environments upgraded from older NAV versions, some add-ins may not carry over automatically and must be reinstalled manually.
