PDFCreator-cli.exe --> shows Dialog instead of silent execution

I want to use PDF Creator CLI to compress PDFs with a PowerShell script.
I tried using the pdfcreator-cli.exe, but it does not process the file but opens a dialog with the settings I put into the command. My expectation would be a silent execution of the command and the output of the compressed file.

The commands I tried are:

'C:\Program Files\PDFCreator\PDFCreator-cli.exe' ProcessFile /File="D:\tmp\test.pdf" /OutputFile="D:\tmp\test_output.pdf" /Profile="High Compression (small file)"

'C:\Program Files\PDFCreator\PDFCreator-cli.exe' PrintFile /File="D:\tmp\test.pdf" /OutputFile="D:\tmp\test_output.pdf" /Profile="High Compression (small file)"

Any help on how to use the CLI in a silent mode without user interaction would be highly appreciated.
