Octopus Crashing

[Dwarven]

I'm trying to get Octopus loaded on 2 machines, 2 clients (1 per machine). I've never tried it on multiple machines before, only the one, and it worked fine.
The server machine works fine, loading the game properly, but on the second machine, Octopus crashes (though the game still loads normally). I'm getting the error message in the picture (I can't seem to get it to copy to the clipboard, and I didn't want to type it out in case I got something wrong).

The server machine is running Windows 7 and the slave machine is running XP. I thought it might be that they were trying to load the game from different directories (Program Files vs. Program Files (x86)), but I've since moved the game into identical directories.
I've also gone over the setting in Octopus itself (following the tutorial), and don't see anything odd.

Any ideas?

Got .NET 3.5 installed? It requires that specific build to work. I've run it on XP, Vista and Win7 on multiple boxes, so I'd suspect that or MSVCRT libs being missing/corrupt first.

Also, try renaming the config.xml file to something else (forcing a new/default config).

I do (or thought I did) have .NET 3.5.
The slave machine used to be my old main machine, but I recently upgraded to some new hardware: it worked fine on the old machine before.

Anyway, I tried reinstalling the .NET 3.5 framework (just in case), and still getting the same problem.
I also tried deleting Octopus and redownloading/starting again from scratch, same problem.

Have you tried reinstalling the C runtimes as well?

Tried redownloading that, too. Still getting the same error message.
I've rerun the windows updates for them, too.

Net Framework is nessecary for Octopus.
I had the same problem before I installed Net Framework 3.5

I've got .NET 3.5, I've got the C++ 2008. Still crashing.

I presume you've actually reinstalled the VC++ runtimes and .NET 3.5?

[Dwarven]

Yop, reinstalled them.
I'd had them before, but I reinstalled them in case they'd become corrupted or something. I ran the windows updates for both of them. I downloaded them from the links in the Octopus tutorial.

I'm at a loss to explain it, then. You could run something like Dependency Walker and see if it found everything, just to double-check. It has to be something related to the changes you made to your system, though.

I hate to sound pedantic, but just to be sure, I assume you're running Octopus in admin mode?
