Hello everybody,That's my problem:I open AutoCAD 2012 from Desktop shortcut. It opens (as "Drawing1")I select from the "File" menu - "Open"AutoCAD freezes, I get Windows message "Close file"If after the 1st step (Opening AutoCAD as "Drawing1") I go to "Options" and add new profile,- no problem, I can open any drawings.But every time I go out of AutoCAD and trying to get I, same problem, I have to crate a new profile to open drawings.Why I need to go out? I have several shortcuts to work in different client folders. Please, anybody, help me to solve this problem. Thank you  

Did these shortcuts work previously?Are you on a network?

Yea, it was working for 5 years.. And yes, I'm on network

So what might have changed to possibly account for the problem?  Hardware?  Software?  Maybe something IT did?

Actually, I'm the IT:) Nothing has been changed. The only thing I did- disabled Interactive Service Detection service (I'm getting endless messages). But, I enabled it again and same results.

AutoCAD2016 works perfect

You are like the fifth or sixth person in the last two days that I read of having this particular problem.  Someone said they thought it happened right after a Windows update.  We haven't experienced it however.

Someone posted this temporary solution at another AutoCAD Help site.  For what it is worth.........****************It must be a Windows update because I got exactly the same problem on
several computers at the same time. I made it work again by placing this
line into the "acad.lsp" file:

Code:
(command "appload")
It brings up an "Load/Unload Application" dialog right when I
start AutoCAD. I just cancel that and from that point 'open', 'saveas'
and 'insert' all work fine.

In your case (LT), try to go to Options>Files tab, click on "Support
File Search Path", highlight any path that opens and then click
"Browse". "Browse For Folder" dialog should pop up. Just cancel that and
cancel Options dialog and you should be good to go. It should fix the
problem for duration of your drawing session. You will have to do this
every time you start the AutoCAD, until Microsoft fixes the problem in
some next update. ***************

It will be the same as creating a new profile when I start new session-it fix the problem for duration of this session/Anyway, thank you for trying to help! 

BTW, the (command "appload") helps!Thank you!

I just read that the problem has been linked to DropBox and the fix is to uninstall the program then reinstall it.

Reinstall Dropbox or AutoCAD?

DropBox of course.  Update to version 8.4.20.
