What are you trying to do with the vector?

2 solutions

C++

vector<byte*> cKey; // Change here


BYTE keyTemp[6];
memset(keyTemp, 0xFF, sizeof(keyTemp)); // Key is FFF...FF
cKey.push_back(keyTemp);

Seems like it is not possible to initialize the array the way you are doing it.
See this link error C3074: an array can only be initialized with an initializer-list[^]

In your case it should be

C++

std::vector<std::array xmlns:std="#unknown"><byte,>> cKey { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF };
</std::array>

or maybe

C++

std::array<byte,> keyTemp { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF };
cKey.push_back(keyTemp);
