The message sequence from this morning prompted me to inquire if anyone can provide help with ATOMS crashing on my own computer. I am running Demeter 0.9.24 on Windows 10 Pro 64. I did a fresh install of Demeter after having removed all older versions of Demeter 0.9, including the Demeter folders in C:\Users\<username>\AppData\Roaming\. My problem is unfortunately simple and something I do not know how to fix: Whenever I hit the "Run Atoms" button, stand-alone atoms crashes. The program simply dies, and no files are written. I am able to enter text, save an atoms.inp file, and reload an atoms.inp file, but "Run Atoms" crashes the program. I have tested this with a simple compound, NaCl, using the attached atoms.inp file. Note that I don't want to work on NaCl, I just used this to test a simple structure. The log file associated with the crash is attached. The log file says Windows 8, but I think this is just hows Windows 10 shows up as that is what I am running, from a clean Windows 10 install. Anyway, when I load this atoms.inp file or enter the same information by hand the program crashes. I was able to load and run this atoms.inp file in the old version of atoms (3.0.1) and produced the attached feff_oldATOMS.inp file. I thus don't think it is a data entry problem. I hope that I have provided enough information. I have no problems running ATHENA, ARTEMIS, or HEPHAESTUS. Given the log file I suspect this is something unique to my computer, but I am stumped as to what it could be as I am running a standard OS with a standard install on Demeter.
