I had a new fun twist in the unsupported world of Navisworks Manage 2014 today...
Model crashes. I click all the little buttons to report the problem. For once, the automotons tell me they have a fix!
The fix? Install Service Pack 1! Awesome!
So I click through, download, start to install (foolishly thinking that someone at Autodesk is paying attention and supporting their "suite" product they upsold us on), only to be told that "the feature you are trying to use is on a CD-ROM or other removable disk that is not available. Insert the 'Autodesk Navisworks Manage 2014' disk and click OK."
Thanks Autodesk!
If you are reading this and haven't bought your Autodesk products, don't buy the suite. Get the individual products you need (not want) as the suites apparently are not supported with the service packs, and at a certain point may simply stop working without the service pack they won't provide you.
