Dear Expers

Again I decided to compile vmd on 64bit windows.
This time I had success and made a vmd_WIN64.exe that can be ran.
But while vmd is loading I get the "Unhandled exception at
0x0000000140117788 in vmd_WIN64.exe: 0xC0000005"
U can also see the attached image: it is exactly at loading when VMD sees
that my system has 27GB of free RAM.
[image: Inline image 1]

I tried to compile all of the plugins(e.g. molefile, etc.), libraries (tcl,
fltk) as well as vmd source code again but this time with /GS and /MTd
The same error happens and surprisingly I cannot see the source code for
debugging in MSVC2008.
It says debugging information cant be found or does not match.
If any one is interested I can give him a complete detailed "how to" for
compiling VMD on 64bit windows.

I have some questions:
1. At this point you see (when vmd crashes) I want to know what is being
2. the default win32 and win64 builds of vmd does not require FLTK package
in the configure file. Should I add this package to build (I mean does it
relate to the problem?)

I am willing to make a win64 distribution and share it with VMD
developers if this problem is solved.
Any help would be appreciated

Best Regards
