Windows – Can’t uninstall a program in Windows 10

I have some files on an external hard drive. The drive is corrupted and I am currently in the process of recovering those files and transferring them from the E:\ drive (external USB drive) to the F:\ drive (a second external usb drive)

E: originally had a lot of programs on it (like everything from Microsoft Office, Adobe Suite, video games, etc)

I'm currently recovering the important files to the F:\ drive, but I have about 10 hours to wait. I decided not to recover a lot of the programs, and just re-download them.

I was able to re-download League of Legends no problem, and I want to put Gwent back on there. Gwent was originally located here:

E:\Games\Gwent\GOG Galaxy

So if I go into Uninstall Programs/Files,
you can see that some of the icons are missing (these would be some programs on the E:\ drive).

If I try to uninstall this program by clicking on Uninstall, I get an error: "Windows cannot find 'E:\Games\Gwent\GOG Galaxy\Games\Gwent\unins000.exe'. Make sure you typed the name correctly, and then try again."

1. I've tried to redownload this program from the internet through their website, but the GoG client won't allow me to change the directory. And the Gwent client won't allow me to click "Install". I have already contacted Customer Support about this. They told me to uninstall the program. >.>

I have also tried going into the Registry – I've looked into HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall and I can't find Gwent or GoG anywhere. (I went through each product key, one at a time, slowly, and I still don't see it)

I have also tried the Microsoft Install/Uninstall Program Fixer from https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed but my program is not listed. If a program is not listed, it asks you for a Program Key… which is not available.

I have also tried using command prompt. I'm not that great with command prompt, but I've tried using E:\> takeown /f Games but I got ERROR: File ownership cannot be applied on insecure file systems; this is no support for ACLs.

I've tried icacls Games /grant administrator and I get: Invalid parameter "administrator"

I thought I could possibly wait for these files to finish recovering from E: to F:, and then format the E: drive, but I don't even know if that would work.

Any ideas?

NOTE: The ONLY visible folders on the E: drive are

• EFI (I did not put this on here)
• Recycle Bin (hidden)
• System Volume Information (hidden)

All of the original files/folders on the E:\ drive are not accessible through a GUI. There are "there", but they are not visibly there. THerefore, I cannot simple navigate to E:\Games (through File Explorer) and click on the uninstall file.

EDIT: Long story short – When you uninstall a program (through normal means) you typically use Control Panel > Apps > Uninstall. The programs I'm trying to uninstall are located on my E:\ drive. (Not C:\Program Files). Some of these programs are located in E:\Games, and some are in E:\Programs.

The E: drive has been corrupted. I'm in the process of recovering files from E: and transferring them to F:. If I try to uninstall a program (through normal means) that is located in E:\Games or E:\Programs, I am unable to. (See lengthy explanation above)
