Issue

You have experienced any of the following problems when using Autodesk® NavisWorks®:

  • NavisWorks freezes during startup.
  • NavisWorks takes an unusually long time to start.
  • There are toolbars missing when you start NavisWorks.

Solution

These issues may occur if the NavisWorks session file, lastsession.xml, has been corrupted due to system crashes or the improper closing of files. To resolve these issues, rename the session file:

  1. Exit NavisWorks.
  2. Using Windows Explorer, navigate to the following folder (depending on which operating system you are using):
    • Windows XP - C:\Documents and Settings\<UserName>\Application Data\Autodesk NavisWorks <Product> 2009
    • Windows Vista - C:\Users\<UserName>\Appdata\Roaming\Autodesk NavisWorks <Product> 2009
  3. Rename the Lastsession.xml file.
  4. Start NavisWorks. A new default version of the LastSession.xml file will be created.
