Chem4Word Error: An error has occured, method not implemented


Hi there,

Yesterday I found your tool Chem4Word because I searched for a tool to create chemical formulas.

I downloaded version beta. This is the first version I installed on my computer which is equipped with Windows 7 x64 and Office 2010.

After finishing the setup I could launch the Add-in and start creating a formula. Then I tried to use the "Import" function and played with it. There was an error message that the web service did not found anything.

From this point the Add-in stopped working completely. Whenever I call the function "Draw structure" a message box appears with German dialog:

An error has occurred
Die Methode oder der Vorgang sind nicht implementiert.

I tried to repair the setup from installer but the problem stays as written above.
So I decided to uninstall it and after a reboot of the laptop the Add-in was no longer shown.

I tried to use the stable version 1.6.1 but even this version comes with the same error message.

Therefore I tried again but it's no longer working. It seems that something was modified which even an uninstall action does not remove from my computer.

What can I do now?

Thank you in advance.

Best regards,

Hi Michael,

Sorry to hear that you are having problems.
  • We do not control the language shown in the dialog, this is done by your system. Can you please translate the error message into english?
  • Can you please try deleteing the contents of the folder "C:\Users{UserName}\AppData\Local\Chemistry Add-in for Word" and try again?
  • Can you also please attach some screen shots and details of what you were searching for?
