You want to know if Autodesk products are supported on non-Microsoft networks.
Autodesk products are designed to conform to Microsoft Network API standards. All other networks that are not Microsoft networks are considered third-party network connectivity products.For the Autodesk software to function properly, your network must provide functionality and performance consistent with the Microsoft network environment. This means that behavior not reproducible between a Microsoft® Windows® server and a Microsoft Windows client is considered a network product deviation, not an abnormality in the Autodesk software. This is reposted from this support page.
I logged this error with Autodesk Support: “…Sometimes Revit 2010 x64 running on my Vista 64 bit machine will not load at all – the program stalls with ‘SecSplashWnd’ showing in the taskbar…”
And they replied with the following: “…There are similar issues logged with the support team.A damaged Microsoft .NET Framework can cause this error. Updating to the latest version of .NET won’t remove the damaged version from the system. Please make sure that you are installing the program when you are logged in as the local administrator of the machine, and that all the other programs are closed, including antivirus, firewall, etc. 1.

I recommend that you uninstall and reinstall .Net in Windows safemode:http://usa.autodesk.com/getdoc/id=TS75218 Clean installation on Windows® XP…” (bold mine)
As you can see, .NET needs to be fixed to correct this error. I haven’t yet attempted this fix, as the problem goes away for me after a reboot – if it continues to be a problem, I will have a go at the steps described.
Let me know if this helped you.
NOTE: The .NET Cleanup Tool link doesn’t appear to work – go to this site to find it.
