FOUND IT!!! Woot!
Here's the long lost install file for Splasher v.1.25!

Took a bit, but I found it via the Wayback archive.
Wow, thanks for finding the install file, that is going above and beyond!
I've downloaded it, and installed it. Looked like it installed fine. However when I run the program, it seems to be working, but afterwards, my screens are still the existing I24 ones.
If you don't mind a few questions, can you look at your files and tell me where you have it installed, and where the screens are saved to?
I have installed CoHSplasher to my CoH Beta folder, install created it in the subfolder CoHSplasher.
I'm running it as admin, and it seems to be going through the motions but I'm not getting a different screen when I launch CoH. I've looked around and I don't see any new files created after I run the screen selection.
You've already done a lot, thanks for everything.
