The add-in entry is missing

Database Tools › Add-Ins has no entry WKL Linked Tables Manager, or the entry shows the message “WKL Forms Object Library is not registered on this computer.” instead of the designer.

The add-in WklExtensions.accda with Microsoft 365 Access (32 bit; see the prerequisites).

• The add-in is not installed for this Windows user, or Access was already running during the installation: Access reads the add-in menu entries at start.
• The menu entry points to a file that was moved or deleted.
• No database is open, or Access runs as runtime (/runtime or the Access Runtime): the Database Tools tab and add-ins are not available there.
• The message about the registration: the add-in runs, but the WKL Forms Object Library is not registered in the bitness of Office (32-bit Office needs the x86 registration).

1. Close Access and run tools\install-addin.ps1 from the release package, which copies addin\WklExtensions.accda and enters its menu items; then start Access again. WklLinkManager.ShowDesigner opens the same designer from VBA.
2. Open a database in the full Access; in the runtime, call WklLinkManager from the application's code instead.
3. Register the components in the bitness of Office (How to: Install the released package).
4. When Access shows a security notice for the add-in, add its folder (by default %APPDATA%\Microsoft\AddIns) as trusted location in the Trust Center.
