Autodesk is reportedly working on a fix for the Inventor 2013 Viewer control. According to Autodesk It appears to be a problem with their compiled control not with how we are trying to use it.
I know nothing about the apprentice.dll other than the Viewer control makes use of it.
Did you turn in a bug report with examples?
I submitted a bug report yesterday. It's the first time I've submitted one to Autodesk support. I haven't heard back yet. Does it normally take them over a day to reply?
Did they give you a timeframe for their fix?
I've never gotten much in the way of feedback from bug reporting. Though I can tell you the more samples / examples you can give that absolutely re-creates the issue is necessary for them to sit up and take notice.
My problem was not always repeatable. Eventually I found out it was only occuring on 2011 Sheetmetal Parts, Assemblies, and Drawings. Standard parts worked fine. Others would test with 2013 solid parts and they would not get an error.
You might try to get your VAR to make arrangements for someone at autodesk development to contact you by email.
I have had a similar problem but with embedding the viewer into Excel and office products. I am running 64 bit Windows 7, Inventor 2013, and Office 2010, I have registered the InventorViewCtrl.ocx via regsvr32 and it stated the install was successful however Excel dose not see the Inventor View Control via the Object->Insert function within excel. It seems to me that, From researching the issue, the control does create a registry entry but it almost as if it places it in the wrong place and Excel can not read link to it.
For all who are having issues with Inventor view control 2013, please try with Inventor View 2013 Service Pack 1.1 if it helps.
Replying the question of message 15 from mecheng:
I have not an idea if Inventor View Control can also support [Create Object]. But the control appears in OLE server correctly. Of course, on 64bits, you will need to register the version in C:\Program Files\Autodesk\Inventor 2013\Bin\Bin32\InventorViewCtrl.ocx instead of C:\Program Files\Autodesk\Inventor 2013\Bin\InventorViewCtrl.ocx,
Please help me to solve this problem http://forums.autodesk.com/t5/Autodesk-Inventor-Cu
Thanks in advance.
