I hate apps that do this. They install items to semi-protected folders, then can't remove their own garbage when you uninstall the app.
You can get rid of the orphaned folder without erasing the entire drive.
Be very careful to precisely follow the directions below. You do NOT want to change permissions to anything but the folder to be removed!
1) Open the Get Info palette of the same folder you posted a screen shot of above. Click the lock at the bottom right if necessary to unlock the folder. Then click the + button at the bottom left.

2) A box will appear. Click on your user name at the right and then the Select button.

3) Your admin account name will be added alongside system, wheel and everyone. Change all accounts to Read & Write. Ignore the mismatch of account names shown below. The point is to add yourself.

4) Click on the down arrow and choose, Apply to enclosed items…

5) Another box will appear. Click OK. When it's done (should only take a few seconds), close the Get Info box.

What you're doing is applying Read & Write permissions to everything within the folder. In particular, you're adding yourself to everything so you have permission to delete all enclosed items.
At this point, you should be able to trash the A8C07287-BOC4-410E-A080-DDBFDBFB9F20 folder.
