Solved it. Found and used this:
Recently I found myself wanting to get rid of Windows Media Player 9. I used AppZapper to get all the application components in the trash, but then I was unable to delete it because files (specifically .htm files) deep within the contents of the app are locked. So after a little research, I came across this fairly simple solution and figured I'd share it:
Warning: Typographical error or misuse of the following rm -rf command can result in serious data loss. Insertion of a space in the wrong place could result in the complete deletion of data on your hard disk, for example. You may wish to copy and paste the commands below into a text editor to verify spacing. Follow these steps to delete Trash for the logged-in user:
1. Use a program like AppZapper to get all WMP components in the trash.
2. Open the Terminal application, in /Applications -> Utilities.
3. In Terminal, type sudo rm -rf[space]. Don't type [space] literally; just press the space bar on the keyboard. Do not press Return.
4. In Finder, open your Trash.
5. Choose Select All from the Edit menu.
6. Drag the selection (all) from the Trash window into the Terminal window. This causes the Terminal window to automatically fill in the name and location of each item in your Trash.
7. Press Return.
Now your computer will be free from Windows Media Player.

Deleting locked files
Locked files can easily be deleted if you press Shift-Option or Option key combination while emptying the Trash (in Mac OS X 10.1 and later). For Mac OS X versions 10.0 to 10.0.4, use Show Info to deselect the item's Locked checkbox.
