Do you solve the problem now?
My friend got that problem last year, and I just asked him. Here is how he solve it:
Choose 5KPlayer and Select the application you would like to remove and Get Info on it, either Command + i or from the Menu File>Get Info.
At the bottom of the resulting window, in the Sharing & Permissions section, change the "everyone" setting to "Read & Write". You will probably have to click the lock in the lower right corner first and authenticate as an administrator.
Once the setting is change, close the Get Info window. You should be able to move the application to the Trash without any trouble.

Version: 5KPlayer 4.2
It plays videos. In my testing, 4k 60fps videos that could play in VLC also play in 5kplayer. Meanwhile, 4k videos that are choppy in VLC are still choppy in 5k player, but maybe a tiny bit better.
The software developer (Digiarty) uses user unfriendly practices that violate Apple's developer guidelines and make me as a user very nervous. These include:
Changing the default application for handling of all media files to use 5kplayer without asking.
Setting 5kplayer to launch upon login but not visible in the user list to remove.
Intentionally making it very difficult to uninstall.
The Mac will always report: "5kplayer can't be moved to the trash because it's open." even after you quit.
The process names are obfuscated so you can't find them to force quit.
Application opens a browser window upon first launch and goes to the developer's site if you don't fill out the registration.
I don't know what hidden functionality exists in 5kplayer, or why they make this software act so much like malware. I don't trust them and will no longer use Digiarty produced software.
Instructions to uninstall:
Right click (or control click) on the application
Select Show Package Contents
Delete the folder inside
Delete the application
Go to: ~/Library/
Open Application Support/Digiarty
Delete the 5kPlayer folder inside
I had an older version, but I was able to force quit (command, option, delete) it and I used AppCleaner which let me move all items to the trash after I gave my admin password. Make sure that all items are checked, since it always leaves a few items unchecked Empty the trash and you will have completely uninstalled the app. I believe that AppCleaner is free and available here on CNET.
The player works well. It has some nice features, such as air-play. It can also take snap shots at any point on a video file, while it's being played.
Doesn't play my blu-ray discs like I thought it was supposed to. It also hijacked my use of Quick-Time player and became my default player. Now, in order to use it, or other video players, I have to do a 2-fingered tap (right-click for Macs) in order to be able to choose another player. I have tried to change the default player back to Quick-Time, but can't find a way to do that.
It works well, but the main reason that I wanted it was to play Blu-ray on my Mac, but I still have to use AnyMP4 free blu-ray player if I want to play them.
