I assume that you are trying to reinstall arcgis pro and have uninstalled previous installations.
If so, and you have already run the *.exe file successfully once, then locate the *.msi in the extracted folder and run it.
The *.exe extracts a *.msi and *.cab file into a sub folder in your download folder.
Anything other than a valid first time install by running the *.exe will most likely cause failure.
... sort of retired...
