FAQ

Why is the COM Add-ins list empty?

  1. Confirm that the corresponding COM add-in program is already installed on the current device.
  2. Open Tools > COM Add-ins again and check whether the list updates.
  3. If the list is still empty, there may be no COM add-ins currently available for WPS Writer to call.

What should I do if a COM add-in fails to load?

  1. Check whether the add-in is compatible with your current WPS version and Windows environment.
  2. Open the COM Add-ins window again and confirm that the target item is selected.
  3. If it still does not work, try re-registering or reinstalling the related add-in program.
  1. Open Tools > COM Add-ins and check whether there are newly added add-ins that you did not intentionally install.
  2. Clear the checkbox for the suspected add-in and see whether the lag improves.
  3. If some add-ins are installed or updated by external software, continue managing them in that external program.
