OpenMx Installation
Hello.

I read that 64-bit version of OpenMx is under development. Do you have any time frame when approximately it will be available? I am just running an analysis that take a LOT of time since 32-bit R uses only 4 GB of RAM.
Is there an advantage of installing OpenMx on a 64-bit Windows machine even though using 32-bit OpenMx?

Thank you beforehand.

Our efforts have been unsuccessful at compiling the NPSOL optimizer for 64-bit windows. OpenMx will crash with the message:

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000000772440c0 in ntdll!RtlUnicodeToCustomCPN ()
from C:\Windows\system32\ntdll.dll

We are currently working on porting the R package Rsolnp into the C language, and then we'll try replacing NPSOL with Csolnp. That won't be ready anytime in the near future. If you need to run OpenMx with more than 4 GB of memory, I would recommend running it under linux.
