I can't install the Epic Installer ("Folder Path" Issue)

I’m currently unable to complete the installation process for the Epic Games launcher.

Here is the sequence of events that has led to my confusion.

I wanted to use Unreal Engine 4, so I went on the website to download it. After making an Epic Games account, I clicked the download button for the Epic games launcher. I went to my downloads folder and double clicked the installer for the launcher. Starting the installation gave me this message: “The folder path to ‘Unreal Engine Stuff’ contains an invalid character”. Then the installation process was canceled. I imagined that I may have downloaded the launcher previously, thereby explaining the existence of the unprofessional file name “Unreal Engine Stuff”. So I looked for the file but couldn’t find it anywhere. I then went to the control panel and found the program “Unreal Engine Launcher”. I tried to uninstall it but I was again given the message “The folder path to ‘Unreal Engine Stuff’ contains an invalid character”. At this point I have no idea what to do. I don’t no the location of these files and I don’t know if I can change the location to where the launcher is installed in.

Any help to explain why this is happening and how I can fix it would be appreciated.
