這是WINDOWS的環境變數與路徑問題，原廠資料如下：
Error: A required .DLL file, AC1ST16.DLL was not found
Published date: 2003-09-03
ID: TS75416
Applies to: AutoCAD® 2004、AutoCAD LT® 2004
Issue
When you start an Autodesk® product, the following error message is displayed:
A required .DLL file, AC1ST16.DLL was not found.
Solution
To resolve this problem, make sure that the folder where this file is located is correctly specified in the PATH statement.
This file is located at C:\Program Files\Common Files\Autodesk Shared.
Ensure that in the PATH statement the C:\Program Files\Common Files\Autodesk Shared entry is spelled correctly and does not have a backslash (\) at the end.
NOTE: If the path statement is too long, the C:\Program Files\Common Files\Autodesk Shared entry in the PATH statement may not take effect. Determine if the C:\Program Files\Common Files\Autodesk Shared folder has been properly read by the PATH statement:
1.On the command line (DOS prompt), enter SET.
在MS-DOS模式輸入SET指令
2. Examine the folders specified in the PATH statement.
檢查PATH變數是否包括C:\Program Files\Common Files\Autodesk Shared
3.If the C:\Program Files\Common Files\Autodesk Shared folder is not listed, move it to the beginning of the PATH statement.
如果PATH變數中沒有C:\Program Files\Common Files\Autodesk Shared 目錄，請到WINDOWS的環境設定中手動加入。
4.Restart your computer so that the autoexec.bat file, which contains the PATH statement, can be read again.
重新啟動您的電腦，應該就可以解決您的問題了。
