I realize that there are a lot of posts about the arc not working and people having problems.
I had problem where arc would not load for me. it loaded to computer and would not open.
no matter what I used to try to open file it would not open adobe, explorer, Microsoft, etc.
so I asked g/f who happens to be computer savy to assist me. she looked at file. when arc down loaded it down loaded with _exe and it is suppose to be .exe
changing that made all difference in world. open down loaded without issue.
my suggestion is for cryptic to tell pwe to fix this to prevent issues in future.
