Visual Studio and Named pipes error: 40

linking back to the previous post, I dont know how useful it will be, my diagnosis could be compeletely wrong. WOW64 normally works perfectly and I have no idea how interprocess communication works in 32 to 64 bit Windows apps the marshalling is probably very interesting.
I also forgot to mention that I was trying to run SQL Server and VS2012 on the same development PC
