I am having the same problem with version 11.3 and 11.4. I updated to 11.3, and had to install .NET Core 3.1. I tried everything said in this thread to no avail, and I also reinstalled the x64 version, x86 version, and hosting version of .NET core. I also reinstalled LaunchBox 4 to 5 times on different hard drives, and every time I try to open the program, I get the same exact pop-up "To run this application, you must install .NET Core. Would you like to download it now?" I can't open LaunchBox in any way, shape, or form. This is quite infuriating, and any help would be much appreciated. Thanks!
