Error installing Hotfix 2021.1.3

[luisPDAN6]

I get the following error in the installation. Any idea how to fix the hotfix installation?

This is not really an error but rather a prompt to access a file needed to complete the hotfix installation.  Due to the fact that there were multiple full product installers released for Revit 2021, identifying the correct RVT.msi file can be difficult.  The following page outlines the simplest method of identify which version of the Revit 2021 full installer was used and provides download links that allow you to download the original full installer with the correct RVT.msi file: https://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles....
