RunWorkerCompleted, the operation is not implemented error

Asked By 10 points N/A Posted on -

I am trying to use Chem4Word add-in for word on my Windows Vista ultimate machine.

I am totally new to this and trying to learn it step by step. When I try to insert anything in my regular Word document, I get the following error message.


worker_RunWorkerCompletes: The method or operation is not implemented.

If I click Ok, on the error message it does not take me anywhere. Again when I try to perform the same action, I receive the error message.

Any help on this is appreciated.

Hi Karenwilson,

You are using windows VISTA, as such. First of all please be advised that the Chem4Word installation should be done, by using setup.exe to install the Chemistry Add-In instead of Chem4Word.Setup.msi.

  • First uninstall the application, and then re-install using the setup.exe.
  • After Installation, you need to activate the application.
  • Open add-ins task pane (File->Options->Add-ins.
  • Select chemistry add-in for word and click the “Go” button to activate the add-in.

It should be working fine.
