Installing Borderlands 2 ver. 1.0.0, Related Installation Problems and Playing Borderlands Cooperative Multiplayer Offline/Home Network/LAN/Between 2 or More Computers in the Same Network

Wanted to play Borderlands 2 real bad with a couple of good friends so I helped them get it all done so we can play but there were many difficulties.

Installation Issues
I installed a Skidrow version of Borderlands just when it came out without installing any extras. Applied and overwrite the crack files and that's pretty much it. The only issue I had was a missing registry key called xmas64. I just downloaded and applied the registry key and worked perfectly.

The first friend I helped had more issues - he game was missing a few .dll files
The list of them:

xapofx1_5.dll Error

If the game gives you an error message when launching Borderlands.exe about missing xapofx1_5.dll
Then download the DLL from here or here and put it in your game’s folder with the EXE.

d3dx9_43.dll Error

If you get this error message when opening the game:
“The program can’t start because d3dx9_43.dll is missing from your computer.”
Then download the DLL from here or here and put it in your game’s folder.

X3DAudio1_7.dll (or XAudio2_7.dll) Error

Same situation as the above. You get get X3DAudio1_7.dll from here (or here) and you can get XAudio2_7.dll from here.

xinput1_3.dll Error

Are you missing the DLL file xinput1_3.dll for Borderlands 2? It may soay “not found” and that “reinstalling could help”. Anyway, this is DirectX related as well. You can do two things here to solve this error. You can grab the latest DirectX by downloading the DirectX End-User Runtime Web Installer OR DirectX End-User Runtimes here or you can try to download just the DLL file here.

As for the second friend, I thought he would have the same problem as the first but I was wrong. His last problem I couldn't solve was  something like "Borderlands 2.exe dynamic link entry point not found" or "msvcr100.dll borderlands 2 missing". My solution? Asking him to reinstall the whole game BUT installing all the extras as well e.g. the Microsoft Net Framework, Microsoft Visual Studio, DirectX and so on that came with the game and it really did work in the end. Installation extras below:

NOTE: I did apply the xmas64 registry on both my friends computers in order to work. The registry key can be found HERE

Getting Multiplayer to Work

After nearly 3 hours of research, I've found out how - with LogMeIn Hamachi and ForceBindIP 

Original Source:http://borderlands.wikia.com/wiki/PC_Connection_Issues#LAN

I made a simpler version of my method based on the given source:

1. Install LogMein Hamachi - Unmanaged Version and ForceBindIP in default install location.

2. Create a new network in LogMeIn Hamachi under the Network Tab.

3. Ask your friends to join the network under LogMeIn Hamachi. Just input the exact network name and password.

   (UPDATE - 11/9/2012)IMPORTANT: MAKE SURE YOU CAN PING EACH OTHER THROUGH LOGMEIN HAMACHI. IF YOU CAN'T THEN TRY TURNING OFF YOUR FIREWALL.

4. That's it for Hamachi. Now for ForceBindIP. First open a new notepad and paste this line: 

   c:\windows\system32\forcebindip x.x.x.x "d:\games\2k games\gearbox software\borderlands\binaries\borderlands.exe"

5.  The only parts that you've have to modify are the orange and green ones. For the orange with the x's, input the IP address from your LogMeIn Hamachi - the one you get right after you created the network. It should be something like 5.x.x.x. As for the green part, put in the exact location of your Borderlands 2.exe file. DO NOT follow the example given above. That's for  the old Borderlands 1 game plus you had most probably installed your Borderlands 2 in C Drive or otherwise.

6. Save the notepad as (name of file of your choice).bat 

7. Run the .bat file and you're done!!! ENJOY :)

   NOTE: I played with friends on a simple home network through cable connected to a router. I didn't manage to play over different networks that are connected to the internet. (UPDATE - 11/9/2012):In game you have to set your network settings to LAN. It should be self-explanatory since that's the ONLY network setting that's usable.
