Similar to how PC scanners work when detecting viruses or any issues needing troubleshooting, EtreCheck creates detailed reports for you, allowing you to easily understand any of the various problems plaguing your PC.
- Troubleshoot installing Office. The issues you encounter when trying to install Office 365, or Office 2019, 2016 or 2013 and how you fix them depends on whether your product is part of an Office for home or Office for business plan.
