Hey All, Thanks ahead of time for the help on this.
I have been working with Navisworks Simulate 2012 for several months now. My I.T. department recently asked me to update my Internet Explorer to version 9, so I did.
Since that time my .NWD files have been Associated with Internet Explorer instead of Navisworks.(I can still open NWD files if I open NavisWorks and open them that way, but I cannot double-click on the .NWD file and have NavisWorks open)
I tried going into the File Association portion of Windows Explorer, but it will not allow me to change the .NWD file. I go and Browse to the Navisworks Directory under Program Files and choose "Roamer.exe" but it will not change inside the File Association Program.
