The PAF installer for Everyone Piano 188.8.131.52 (uploaded: 26 Jan 2016) seems to be corrupted:
I had tried downloading from MirrorCreator & SendSpace, but the respective files (MD5: 40014eb37e2db58927e52fc330d9ca45) all show the same error as follows:-
Installer integrity check has failed. Common causes include incomplete download and damaged media.
Contact the installer's author to obtain a new copy.
