Need WPI Script with music on/off, percentage, time elapsed/remain & extracted file

[harshlohaan]

I need a WPI Script with music on/off functionality, percentage progress, time elapsed & time remaining and progress bar of current extracted file shown side by side.
And with nil errors like that runtime error after installation and during uninstallation.
Also, in the razor12911's WPI (update 3) script I have to unlock the lock screen again and again due to click somewhere else than the installer window itself. (Like refreshing in between the setup) I don't literally want the lock screen to be removed but want to unlock it for once only during the launch of setup as in CorePack repacks.
Thanks in advance...
