There's a double-close of a registry handle in ff7.exe:
.text:00407625 8B 55 E4 mov edx, [ebp+hKey]
.text:00407628 52 push edx ; hKey
.text:00407629 FF 15 10 60 7B 00 call ds:RegCloseKey
.text:0040762F 89 45 F0 mov [ebp+var_10], eax
.text:00407632 EB 07 jmp short loc_40763B
...
.text:0040763B loc_40763B: ; CODE XREF: sub_4075B0+82j
.text:0040763B 8B 45 E4 mov eax, [ebp+hKey]
.text:0040763E 50 push eax ; hKey
.text:0040763F FF 15 10 60 7B 00 call ds:RegCloseKey
This sets off the debugger. The patch is simple: EB 07 -> EB 11 to skip that code when doing that jump.
