When I asked you for a screenshot of the About Camera Raw splash screen, you responded by saying that it was the same as mine. I should have been more specific. I am looking for the version number of ACR as highlighted in the following screenshot:

I don't believe you have the same version as mine because your file size (shown in your latest screenshot) is different.
There are a couple of other suggestions I have:
Rename the File Formats folder to something like File Formats Original. Then try to Install Camera Raw again from the Help Menu.
Alternatively, install the latest version of Camera Raw manually. This requires you to follow these instructions precisely:
- Rename the Camera Raw.8bi file by adding a tilde prefix (~Camera Raw.8bi)
- Go to the Adobe Camera Raw plug-in installer website and follow the instructions to download and install Camera Raw version 16.4
- Navigate to the following folder: C:\Program Files\Common Files\Adobe\Plug-Ins\CC\File Formats and copy the Camera Raw.8bi file
- Navigate to the the following folder: C:\Program Files\Common Files\Adobe\Plug-Ins\Elements24\File Formats and paste the Camera Raw file into the folder.
