AutoCAD 2011 file


Novice Member
yesterday I worked with the AutoCAD 2011 file. Everything was normal. The program was closed in the usual mode. Today I open, and program gives out me a window with the message: "Failed to open the drawing. It contains incorrect or corrupted data." .bak file is also corrupted!

There is file in the folder with the document an acad.err which says: "FATAL ERROR: Unhandled Delayload "acurlutl18.dll" Module Not Found Exception at 7c812aebh
09/07/2017 at 09:53:30.281 drawing: "

Have you tried Recover?

What to do?

- select menu File -> Utilities -> Restore...; –

specify the file of the drawing which needs to be restored. I

n the File Choice window, and press "Open".

Standard recovery tool will attempt to recover the drawing. If attempt of restoration is unsuccessful, there will be a window with Message of AutoCAD

"The File of the Drawing Can Not Be Restored" .

Then you must find the latest backup of the damaged drawing file (with the extension .bak) or the AutoSave file (.sv$). Change the extension .bak (or .sv$) on the .dwg extension.
