pyopenms DLL issue

[AUldry]

Dear all,

I'm downloaded and installed MS2Rescore-v3.0.3-Windows64bit.exe on our Windows 10 Enterprise server. It installs without issues, but we get the following message when the program starts:

ImportError: DLL load failed while importing _pyopenms_1: A dynamic link library (DLL) initialization routine failed.

I'm a little hazy as to whether this windows executable comes with python stuff all packaged in, or whether it's trying to use our pre-installed python install. We do have indeed python 3.9, there, and pyopenms 3.0.0. Import pyopenms does not complain when invoked.

Any idea what is to be done? Thanks in advance!

Best wishes,
