Don't mix the two installations, patched and unpatched. You
will end up with a corrupted call stack.
Do it exactly the way it's described:
- unpack the base game,
- unpack the patch - note that you should get many warnings about files being overwritten. If you're not getting them, you're doing it wrong,
- start the patched game,
- start a new playthrough.
Sometimes a patch is released which doesn't require you to start a new game. In this case, save the game while on the brothel screen, exit, patch, start the game, load the save. Restoring a save made anywhere else is not supported between patches.
And note that the two errors you posted are different. I'm not using 7zip so I might be wrong, but the second screenshot shows your game file was corrupted in some way. Try redownloading.
