We've followed the cleanup process indicated in the Autodesk Knowledge Base......didn't do a thing. Still get the Missing Language Pack message almost all of the time.
What version are you using? 2009?
This removes the virus from the computer, correct? The dwg file is still "contaminated"? Is there a way to decontaminate the file?
Have you customized you parts with Part Builder?
We started getting this come up at our office last year and so I had everyone go through the instructions for the acad.vlx virus and it went away (or we stopped getting the messages anyway). But as soon as I installed C3D 2011, I am getting it again on every drawing I have opened so far (which is only a few - I am not sure if I should open too many). I went through the instructions from here http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=13717811&linkID=9240617 again for my 2011 installation and I still get the messages. These are drawings that were created by me and used only by me from an English based install.
One other thing. No one in the office ever found the logo.gif file, acad.vlx file, or the string of text mentioned in the virus fix.
I came across this forum when I was searching for an answer to why I was getting the missing language pack pop-up suddenly in Civil 3D 2013. It first started when I received a drawing from outside of our company. It has now since spread to new drawings we created inhouse from our templates. I reviewed the instructions from here http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=13717811&linkID=9240617 and never found the the logo.gif file, acad.vlx file, the string of text mentioned in the virus fix, or the ACADLSPASDOC system variable changed to 1. I've wblocked items out and even backsaved files. This is only a temporary fix, since later on when the file is opened it eventually displays the missing language pack dialog box. It's quite annoying especialy since it seems to be affecting another computer in my office. Is there a solution to fix this?
We are using Civil 3D 2013 Service Pack 2.
