Yes, I am sure.
For my tests I use a virtual machine with Windows 10 64 bit virgin, no other software installed.
I install AutoCAD 2023 from scratch and the start suite doesn't work.
With the same procedure, on the same cleaned virtual machine, but a previous version of AutoCAD it works correctly.
On another (work) pc where I have various AutoCAD and other software, it works correctly.
I don't use .NET but only LISP and OpenDCL.
I solved my problem with "PackageContents.xml" however I haven't finished my tests yet.
Thanks for your help.
