I guess your customer is using a terminal server or Citrix. The ruls to install software are different for those. You may want to create a separate thread for that.
Anyway, neither mscomctl.ocx nor mscomct2.ocx have anything to do with Word automation. Most likely you application (user running it) is not authorized to use Word or Word automation. Again I would recomend to create new separate thread about that and provide more details.

>my client formerly had workstations with a hard drive on each workstation and on which was installed MS Office. i used to register the mscomctl.ocx and the mscomct2.ocx DLL files on each work station and was able to open MS Word files that were stored on the server in a folder and fill them up with data from my database.

>now, however, he has only dumb terminals (thin client machines) which connect to the server. As a result of which i cannot register these .OCX files. This results in some error popping up every time he tries to open the MS Word file via OLE and populate it with data from my software/database.

>my problem today is that after this change to thin client machines, my program cannot open the MS Word files like before and some error is thrown.
