I use the custom-transformer WordToPDFWriter. On my desktop it works fine. When I run this workspace on the server I have a failure. What causes this error and how can I solve this?

Hi,

The WordToPDFWriter has 2 dependencies, as you mention yourself in your post...

So, the question is:

1) did you import the comtypes python package to your FME Server (for more information, see: Importing Custom Python Modules to FME Server)

2) is Microsoft Word installed on your server?

BR,

Hello,

Would you be able to create a case with the following information-

• Build and version of FME Server
• Build and version of FME Desktop
• Full job log file on the Server
• Said workspace with sample data

Good day - I am having the same error. I just validated that the user who runs FME Server (Flow) has an E5 MS License and I installed Word to the server. I have further installed Comtypes using the FME process. What is very odd, I run the workspace which is simple ( Creator then WordToPFWriter ) using the same account that the FME services run under using FME Desktop (Form) and everything works fine. Publish to FME Server, which is the same machine we just ran the workbench on and I get the same errors as reported by Perry:

Why does this work nicely in the desktop workbench for the exact same user that runs the FME services on the same machine where FME Server is located.

Issue is when run via FME server we get errors and no document is created?

Thank you
