0.78 has been out since 29 October 2022.
PuTTY 0.78 is in Patch My PC since it released! If you are seeing PuTTY 0.77 in red color, that means you have PuTTY 0.78 and PuTTY 0.77 installed at the same time and you need to manually remove PuTTY 0.77.
If you don't have PuTTY 0.77 installed, then there must be some leftovers from that version that needs to be removed.
