Have been having this trouble since I installed 2014 and happened again this morning. Thought previously Inventor was having trouble with my 2012 files but the IDW I tried to open this morning I have edited before.
I opening the main assy, opened a sub assy, made a few changes then tried to open the IDW file. The windows hourglass displays for as long as I am willing to wait. I click again and the screen goes gray over my assy and Inventor comes to a complete halt.
I have to use Windows Task Manager to shut Inventor down and open the IDW file first. SAfter I get an IDW open it seems I can open more of them until it happens again for no reason and no logical sequence.
Build 170, Release 2014 RTM, Update 1
Thanks
You might try installing update 2:

Update 2 did not fix the problem. The same IDW file I edited this morning still took Inventor to a complete standstill.
Also when I check in my main assy to our vault Inventor crashes checking in the top assy IAM file. Everything else seems to be updated in the vault. Interestingly I got that IDW file open and when checking it in the main assy IAM file is checked in.
Many thanks to report the issue to us! Could you attach the dataset or send it to me @ river-yijiang.cai@autodesk.com for further investigation?
