oh yes your are right
We found now a bad font on our System.
When we delete it Inventor works.
But why this error mesasage ?
It doesent fit to that.
Well we gave up trying in the end (since no useful advice came from Autodesk) and bought a new PC with Windows 7 and thus far Inventor seems to work fine on it.
Extremely disappointed to not have had a proper solution to this problem.
Problem solved. Got a new machine at work with WIndows 7 on.
Such a shame there's no support for older platforms. Still fairly cheesed off there was no definitive solution to the problem on XP based machines.
I am also having this problem. I am a student running windows xp (sp3) and have reinstalled inventor pro many times, as you have all said, it crashes at startup and then sends an error report. Any help would be much appreciated.
Everyone should try SolidWorks, it is a better program. SolidWorks is more user friendly, easier to manipulate, and hasn't crashed or given me any problems. SolidWorks is also more affordable than Inventor, and more companies use SolidWorks than inventor because of the price.
OK so i was having this problem along with 3DS max saying something about the .NET framework. So I downloaded the latest >NET (4.5). And Still nothing. Then i went into windows features and realized .NET wasn't even turned on (although i worked before so I don't know what changed or when) but it works now!
