These issues can grind your workflow to a halt, but don’t worry. This guide breaks down the most common installation failures, explains why they happen, and gives you step-by-step fixes to get you up and running quickly.
Install Octoparse AI
First: Check Your System Requirements

How to Fix Common Errors?
If the standard install fails, you’re likely facing one of these common issues. Let’s break down how to fix each one.
1. Error 0x80070490: Installation Wizard Fails (“Element Not Found”)
If .NET 4.8 is not installed or the installed .NET 4.8 has incomplete functions, the following error prompt usually appears: 0x80070490 - Element not found. (0x80070490 may also be other codes). At this time, the problem can be solved by manually installing .NET 4.8.
Solution: Download the offline installation package of the relevant components and install it manually.
