Downloading the dpapi.dll file
We don't advise to download the dpapi.dll file and copy it to the Windows system directory. The software's creators almost never circulate the DLL files, they are always part of an installation set. It's the installation set's task to perform the sufficient verifications before the installation. An incorrectly installed DLL file may cause the system's complete inability to function.
