What is PYTHON-DLL-LOAD?
Error loading Python DLL is a low-severity software runtime issue. Python cannot load the required DLL (python3xx.dll). The application or script does not start. This can also stem from missing VC++ redistributable package. Follow the steps below to fix it.
Common Causes
- Corrupt Python installation
- Python version conflict
- Missing VC++ redistributable package
Step-by-Step Fix Guide

Frequently Asked Questions
The leading cause of PYTHON-DLL-LOAD is corrupt Python installation, though python version conflict and missing VC++ redistributable package also show up in our reports.
Most PYTHON-DLL-LOAD reports resolve after "Reinstall Python". The rest of the guide above is there for the cases that don't.
As a low-severity issue, PYTHON-DLL-LOAD is more of a stability annoyance than a hardware risk — the steps above should clear it up.
You shouldn't need to. Work through the guide above first — a reinstall is only worth considering if none of those steps help.
