I am getting an "patch failed to apply with error code 18. Failure opening new file:D:\20\forms\1040_20\pspdfs\F8915ES_SW_1.pdf" so i cant update 2020 proseries at all

[Just-Lisa-Now-]

Close ProSeries.

Go to the Windows Programs menu and find ProSeries 2020 and use Tools > Repair updates 

Now open Proseries and try to run updates again.
