Hi,
Thank you for sharing your question.
I understand how concerning it is when AutoCAD 2006 freezes whenever you use Save or Save As, especially when you simply want to save your work as a .dwg file. It can be very frustrating when an older program becomes unstable on a newer operating system.
This issue usually happens because AutoCAD 2006 is not supported on modern versions of Windows, and the Save dialog depends on legacy components that no longer function correctly. When AutoCAD cannot load the Windows file dialog, it can lock up or stop responding. In many cases, enabling the built‑in AutoCAD “classic” save dialog or running the program in compatibility mode allows files to save normally again. You can try adjusting AutoCAD’s file dialog settings by entering the FILEDIA command in AutoCAD and setting it to 1, which forces the standard save window to appear. Running AutoCAD as an administrator or setting compatibility to Windows XP or Windows 7 may also help stabilize the save process.
May I ask which version of Windows you are currently using with AutoCAD 2006 and whether the program has worked correctly on this system before? That can help determine the best next step.
Please feel free to follow up with what you find or if you’d like help walking through the settings. I’m here to support you until saving works normally again.
I hope this helps
Best Regards,
Noel
