I opened a case with my VAR on Monday, and they subsequently opened a case with Autodesk on Tuesday. I sent them system info, as well as a link to this thread to help describe what was going on. As of Wednesday morning, Autodesk had stated they were having trouble reproducing the issue, and had several questions about workflow and order of operations of the install. I replicated the issue on my workstation and answered the questions. As of this morning, Thursday, I haven't gotten an update from the VAR or Autodesk, but I figured I'd give them a couple of days to see what they could work out, especially since everything works after rolling back to Inventor 2019.1.2.
From my experience and everything I've read on this thread, the issue seems very enigmatic, and I would completely believe that they are having trouble reproducing the issue in a way that allows them to troubleshoot it effectively. Case in point, another of my workstations here, without any changes since yesterday, is now allowing Copy Design, whereas it was erroring out yesterday. A third workstation here is still producing the error. Both of those workstations are running the 2019.2 update.
I don't have a restriction on remote access, but Autodesk and my VAR haven't requested that yet. I'm willing to help out in any way that I can - it would be nice to have spell check, but I'll choose Copy Design over spell check all day long.
Regards,
Eric
