In this article, I will look at the Microsoft Office installation error: 30175-45.

This error may occur because you have previously installed Office and the application conflicts, or the installation was interrupted and you resumed the installation.

- In this case, you should use the official Microsoft tool - Microsoft Support and Recovery Assistant.

You can download and use the instructions in our previous article.

After you use the application to delete the remaining Microsoft Office files, repeat the Microsoft Office installation.
