How to fix "Windows Installer package DLL" problem when you try to uninstall a program

The following error appeared on a customer’s computer when we tried to uninstall a nasty program named “SavingsBullFilter” (or “SavingsBull”) : “There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run.  Contact your support personnel or package vendor”. 

The error probably appeared because the program installation was corrupted or after performing a malware cleaning procedure on the same computer, without prior uninstalling it from Windows. For that reason, we installed the unwanted program again in order to try to uninstall it again from Windows Control Panel (Add/Remove Programs). But the “Windows Installer package..DLL could not be run” error message appeared again during the uninstallation progress. After some tests, we finally found the following solution to bypass the “Windows Installer package..DLL could not be run” problem:
