64-bit windows installer

[Andrew Parsloe]

I've downloaded and installed the 64-bit windows installer. No problems 
with the installation. But the first trial document I tried triggered an 
error. If there is a preview to be formed (e.g. a math inset with 
preview on), I get the error: "dv2dt.exe System Error. kpathsea631.dll 
was not found." If I click OK to remove the message and wait, eventually 
the preview is formed. Compilation to pdf still works.
