@datboilizzy so it doesn't look like this (See attached image) ? Theres no box you can tick? If not, thats bizarre. There is another route. One I'm not familiar with doing, but you could try using command prompt instead.
That is the other method I see people sharing to get things going. You would target the same file, but through command prompt instead. I don't know if we're allowed to share non-ea links so I'll just copy and paste the text.
How to run a program on Command Prompt
Here is a list of steps to help you run a program on Command Prompt:
1. Open your Start menu and type "cmd" in the search box
Locate your Start menu in the bottom left corner of your screen and click on it. In the white search box next to the Windows icon, type "cmd." Command Prompt is the first search result.
2. Click on Command Prompt to open the application and type your first command
Right-click on the application and select "Run as administrator," then a new Command Prompt window opens. This opens a black screen with plain text.
3. Determine which program you want to run
Find the folder with the file you want to run. It's important to mention that Command Prompt can only run programs that are installed in Windows-created folders. You can add a program's folder to the Command Prompt list to run that program within the application.
3. Find the file path of the folder with your exe program
Type "cd [filepath]" into Command Prompt. This allows you to find the folder that contains the .exe program you want to run. In a File Explorer window, you can open the specific folder and copy the file path located in the address bar at the top of the window by pressing C and Ctrl. For example, you can run Google Chrome by locating a folder titled Google Chrome in your Program Files. The file path for that file is "C:\Program Files\Google."
4. Replace "[filepath]" in the Command Prompt window with the file path you've copied
Replacing this file path allows you to run both commands and the desired program. You can then press the Enter key on your keyboard. This takes you to the selected file path in Command Prompt.
5. Type "start [filename.exe]" into Command Prompt, replacing "filename" with the name of your selected file
Replace "[filename.exe]" with your program's name. This allows you to run your program from the file path. For example, you can run Google Chrome by typing "Start Chrome.exe." You can then hit "Enter" on your keyboard, and the program starts running
