On behalf of the "NPSWF32\" and "RipForGames.bat Not Found" problem

My solution to this problem was to execute the following line in CMD:
"takeown /f C:\Windows\winsxs /r /d y"
In order to be able to modify the permission of the Administrators group so the setup would work correctly.
After running the line and waiting for it to finish, head over to the C:\Windows\winsxs folder, right click it and select propertires -> security -> advanced. Locate the Administrators group and double click it in order to give it Full Control. Apply changes and then run the setup.exe
My windows (win7) reported the process to be hanged up, but "waiting for program to respond" worked for me.
You might want to change the security policy to default after installing
