Apologies for reviving a months-old thread, but I stumbled upon your post while hunting for similar information. It's unfortunate that Composer Home 3.2.4 isn't opening up on your Windows 11 Pro. I understand how frustrating it can be when software doesn't work as expected. I recommend checking out the Cheap Windows 10 Key Reddit sub. They often share helpful insights and tips that might assist you in resolving compatibility issues. It's a great community to connect with fellow tech enthusiasts who might have encountered similar problems. I'm new to this forum as well, and I'm always on the lookout for useful information and solutions. Hang in there, and hopefully, you'll find the solution you're looking for.
