catsxp works smooth on Win7 ESU build 7601.27219 (server2008r2 latest updates throught bypassv12 tool)
Was able to patch Edge 127.0.2638.2/126.0.2592.x/124.0.x (x64 versions) and run them successfully. Also tried patching versions 127.0.2639 and above but they fail to run and most likely need additional patching.
Patching Microsoft Edge is a bit complex , even Blaukovitch noticed it, since there were always errors with the memory (RAM memory) apparently because some process was corrupted causing high memory consumption. That's why in some of his publications he only provided the x86 link and not x64 (apparently due to his memory errors).
I guess it helps in a sense that patcher works against different versions of Edge and with right set of dll files. These can be copied from 125 release in GOOGLE_CHROME_Windows_7 repo.
