The Universal Installer and Live Update will still download files again and again after using this Auto Manager.
From this sentence, it doesn't seem you understand what is happening and what this installer does.
The WHOLE issue with the Live Update downloading the files over and over, doesn't mean the Live Update is "bugged". In fact, it's exactly the opposite, it IS working correctly and it correctly detects some files are outdated so, it correctly download them. However, the local cloudflare node in your area, is NOT serving the latest version we have online, because it still hasn't replicated the files, because of too much traffic due to the release, they have been slower than normal.
So, on the next try, the Live Update correctly detects your file is STILL outdated, and it tries to download it again, and again it doesn't get the file it should have.
The Live Update is doing its job. In fact, it would have been a bug if it did *not* tried to redownload it again!.
So, what this installer does ? It doesn't download *anything*, it simply includes all the important files that make all of GSX code ( = programs without objects or textures ), which are the exact copy of what's online now, that you were supposed to get.
So you only need to install this, and don't worry about Live Udpate, that's what the fix was about, to allow users affected by a local Cloudflare node being too slow getting the files, to get the files IN ANOTHER WAY.
