1. When the adlmint.dll file is used instead of registration, I want to know whether you have backed up the original file in adlmint.dll. Adlmint.dll file, restore the original backup adlmint.dll to the installation directory of AutoCAD20 10. If there is no backup, you can find your way to the unzipped folder.

Path: drive letter: \ unzip folder path \x86\acad\Program Files\Root\. Find the installation directory and restore it.

2. First, unzip the registration machine to the installation directory and start AutoCAD 20 10. You will be prompted that you need to activate it. For WIN7 systems, right-click and select Run as Administrator to open the registered machine. (Note that there is a sequence here)

3. Start AutoCAD 20 10, and you will be prompted to activate it. Copy the application code, open the registrar, paste the application code, click "mem Patch" in the registrar, and then click "Generate" to generate the activation code. (Pay attention to the prompt of success), this is very important, otherwise the generated activation code will be wrong.

4. Copy and paste the activation code obtained from the registrar into the activation dialog box of AutoCAD20 10, and then click Next. Prompt "Activation successful"!
