[mpich-discuss] lnk 2019 error, hellow world on windows 7 (64bit), VS2008

[Ryan Price]

No I haven't had a chance to follow section 9.4 but I installed from the
binaries as an administrator previously. I plan to reinstall VS2008 with the
64 bit components installed and reinstall the x64 version of MPICH2 and then
I'll report back. I suspect that is the cause of my problems but won't have
any free time to reinstall until my current project is finished.

Thanks,

Ryan
