Autodesk – DWG Launcher wigged out fix

7/8/2009

Please remember we have moved to http://johnevansdesign.net Come visit us there.

This has been a pain in numerous people’s sides for a long time.  One day you love it and the next day you hate it. 

The DWG Launcher

This gizmo is the thing that loads the drawings from remote requests, based on the registered DWG extension. AcLauncher.exe

Since Autodesk is trying to spread it’s trademarked use of DWG to numerous platforms, it needs some flexible way to allow users to open the DWG easily through explorer and other applications. 

How this works

When the OS sees a DWG file request sent, it uses the DWG registered app to open it with. In this case it is the DWG Launcher. The application uses registry entries to figure out which version of what application to use.  It is fairly simple, except there is nothing evident about it, and it gets fouled up. 

The registry settings governing this work something like a flow chart:

  1. Windows initiates default dwg app ->DWG Launcher
  2. Launcher reads shell DWG default Application –> AutoCAD
  3. Launcher goes to AutoCAD and reads launch instruction –> AutoCAD r18 exe path
  4. Launcher executes launch statement with requested dwg file

Most users will never have a problem with this since they only use 1 type of DWG application.  Actually, most users of differing DWG apps never have a problem.

Inventor – DWG wizard Selective import is empty

Here is a problem some VISTA users have.  The DWG import wizard viewer “Selective import” control is empty.  One reason is of course VISTA, but another may be because of constant uninstall and reinstalls of Design Review.  I have not confirmed the latter, but I do suspect it.

I went looking for some info on this, and found the ‘known issues’ list in numerous places.

The DWG import wizard viewer “Selective import” control is empty: You may notice in the DWGIN wizard’s viewer page that the “Selective import” control is empty (this control lists the layers in a DWG file). This indicates that a module needed by the viewer is not registered (because a lack of user privileges).

In Click Start > locate the program for “Command Prompt, ” and right-click it as run the program with the option “Run as administrator”

To register You cannot start the cmd.exe from Run…” menu for this procedure. When the command prompt is active, navigate to where dxoemviewer.arx is located (c:\program files\aoemview 2008, by default), and then enter the following:

Regsvr32 dxoemviewer.arx
