I do something like this in a batch file to guarantee running 32-bit from a
64-bit command prompt:
@rem Workaround allows msys/cygwin rxvt to run on Windows x64
@rem (SysWOW64\cmd.exe runs as 32-bit)
@rem
@if "%PROCESSOR_ARCHITECTURE%" equ "AMD64" (
@"%WINDIR%\SysWOW64\cmd.exe" /c ""%~f0" %*"
@exit /b 0
)
What you're asking for is the inverse: running a 64-bit program from a
32-bit program. I'm not sure what the right file reference to use is to do
this, but I'm sure you can do it..... If nobody else replies again to this
thread sooner, I'll try to figure out the right invocation and pass it
along.
Good luck,
David
