Facing fatal Error In AutoCAD lt 2016 0x7ff9799b0005

[karanwalunj]

Recently I'm facing trouble with AutoCAD LT 2016 i use Solid edge and then export Draft file to CAD and then use for it for other purposes but recently it started showing some fatal Error and i only experience it with solid edge exported files & not with regular files which are orignally created in AutoCAD. It says 0x7ff9799b0005 c:\program\files\autodesk\autocad lt 2016\acsceneoe.dbx. I'm attaching Screenshot of the error dialogue box. Please help me resolve this issue as soon as possible

Win11 is not supported. That may be your biggest problem. But you chose not to mention that, aka a major change to your 2016 setup. Oh well.

Other than ensuring you have the 2016.1.2 update installed https://knowledge.autodesk.com/support/autocad-lt/downloads/caas/downloads/content/autocad-lt-2016-s... so your old software can work best in Win10 (and hope it fixes Win11's issues), either your SolidEdge changes, or your export method from SE changed, or you need to roll back to Win10 or Win7.

You might also need to seek support from SE's forums in case others have other tips you can try https://community.sw.siemens.com/s/topic/0TO4O000000MihiWAC/solid-edge
