That's a common Windows Dynamic Link Library file for every OS. So placing it inside the BIN folder solves the in-game 'Map/Custom Map' Download issue, as well as other server/MP file transfer issues ?
So, strangely it seems the game loads this .dll file from inside the folder under Win 7, and not directly from the Windows path. Anyhow, I don't have Win 7 with me right now. But others should try this out.
I think the above file has already worked fine for 'Mr.Streak', and he has a 64 bit Win 7 Home premium as told by him ??
As far as I know, the 'winhttp.dll' file is the SAME for every OS (32/64 bit), but under the 64 bit Win XP version, there are sometimes 2 'winhttp.dll' files. One is which lies under the SysWOW64 folder, and the other is under the system32 folder. e.g.
But the file under the SysWOW64 path, is the common one which is also found under 32 bit Win XP. @Fartcryer15 can upload the files again if possible, taken from a 64 bit XP. But I don't think doing this will make any difference, as the Winhttp.dll file is almost the same.
