Run python script that interact word (pywin32) in the batch mode (Task Scheduler/Windows Service)

Question

I have written a python script that takes RTF files that my system is creating and converting it in to DOCX format.
I accomplished this with pywin32 library. By this library I’m able to open Word and save as DOCX.

def ConvertRtfToDocx(path, file):
    word = win32com.client.Dispatch("Word.Application")
    wdFormatDocumentDefault = 16
    wdHeaderFooterPrimary = 1
    doc = word.Documents.Open(path + file)
    for pic in doc.InlineShapes:
        try:
            pic.LinkFormat.SavePictureWithDocument = True
        except:
            pass
    for hPic in doc.sections(1).headers(wdHeaderFooterPrimary).Range.InlineShapes:
        try:
            hPic.LinkFormat.SavePictureWithDocument = True
        except:
            pass
    doc.SaveAs(str(path + file.split(".")[0] + ".docx"), FileFormat=wdFormatDocumentDefault)
    doc.Close()
    word.Quit()

This have to run on demand, as its scanning the directory and converting it as soon it finds it.
Long story short, I was able to run it successfully with simple cmd.
However, when I ran this as a service (NSSM) or "run as a batch job" its fails.
I’m assuming its because the python has no display to open the Word to…

My operation system is Windows Server.

I will be appreciated if someone could help me with this task.
One more note, it will be great if the solution will be use as less third-party software as it possible.

Its turnout that the problem wasn’t about the virtual display. The problem is that Microsoft does not allow using of Office application in batch mode by default. That why in 2008 they change the windows in the way that just logon regular users can make a use of Office and Office objects.
But there are a few ways you can overcome this obstacle.

The easiest way is to create these paths –

Windows Server x64
C:WindowsSysWOW64configsystemprofileDesktop
Windows Server x86
C:WindowsSystem32configsystemprofileDesktop

This way you are creating the “environment” for the system user (Admin). And you can run it as a batch job via Task Schedular, windows services etc.

But if you if does not work for you this way, I recommend you read this links –
