Can't open DWG file from e-mail

[Anonymous]

Hi,

I had received a DWG file from my associate through e-mail which she had saved from AutoCAD as a 2007 year format.

I have AutoCAD Architecture 2011 and should be able to open any DWG file, correct? But I can't seem to. When I try to open it, a message pops up that says, "Drawing file is not valid". I have gone into the file properties and I have full accessibility to the file and the "read only" option is unchecked. 

Any suggestions on why and on how I can open the file would be great.

Thanks!

"Drawing file is not valid" means you got a dead file: ask the sender to ZIP and re-email the file to you WITHOUT them doing anything special to it.

Remember to take it out of the email, park it on your PC, then open.
