NetWorker : Installing NMM 19.9 on SQL Server with SSMS 19.1 Does Not Display in Toolbar

• NMM 19.9 installation on SQL Server that has SSMS 19.1 does not display in SSMS toolbar.
• The Actual plug-in is successfully installed.
• The plug-in can be launched from the Start menu shortcut, and it backs up successfully.

The root cause of the issue is the use of VSIXInstaller to install SQL Server Management Studio extensions, which is no longer supported by Microsoft since SSMS version 18.x.

• Microsoft has discontinued the use of VSIXInstaller with SSMS 18.x and later versions.
• This change affects the installation and display of extensions, including the NetWorker Module for Microsoft (NMM) 19.9, in the SSMS toolbar.
• The issue is not related to the actual installation of the plug-in, which can be launched from the Start menu shortcut and backs up successfully.
• The problem lies in the fact that the plug-in does not appear in the SSMS toolbar due to the change in the installation process.

Caution: This issue is specific to SSMS 18.x and later versions, and users with earlier versions of SSMS may not experience this problem.

• Some editing tools like Notepad, do not retain the required format.  
• When creating the package definition file, use the attached file NWSSMSVSIXPackage.pkgdef instead of creating it manually to ensure the correct formatting.
• After creating the package definition file, restart the SQL Server Management Studio to apply the changes.
• Verify that the NetWorker Module for Microsoft is displayed in the SQL Server Management Studio toolbar.
