AutoCAD 2010/2011/2012 DWG Format

[#1]

We are running AutoCAD Architecture 2012 on a Windows 7......64bit workstation and AutoCAD will suddenly crash for no apparent reason. When I look in the event log it makes a reference to the AcDB18.dll   has anyone seen this before....?? Is there a way to correct this problem....??

Thank you,

Vince

What can be done to resolve this....?

Is there any error message on the screen? Are you all up to date on service packs and hotfixes (http://usa.autodesk.com/adsk/servlet/ps/dl/index?siteID=123112&id=2334435&linkID=9240618)?

I believe we had Service Pack 1 installed.....!

When the crash occurs I get a message stating AutoCAD can not continue.....Exiting AutoCAD....!

When I look in the event log there is a reference made to the AcDB18.dll....?  which I do not know if is related to the reason AutoCAD crashed in the first place.

Regards,

Vince

.dll sometimes can be corrupted

If you have another PC with same operating system, check for the size of the file.

The same happened to me with the Autocad Architecture 2012 ,and I´ve made an experiment: Y crated a model using the new tools : walls, windows blablabla and the system was so cramped that I could´t make a line. Then I tried making the same model in the old fashion way (poliline, extrude, height...) and it run perfect... so in conclusion the new tools are unusefull

I am running AutoCAD LT 2012 on Windows 7, 64 bit. Stops working after plot-save-close or plot-close.

Ran all available Service packs with actual executable files.

Am running as admiinistrator.

What's the deal?
