I installed two CAD Ivy, one in 2008 is no problem, and the other in 20 12 is the same as the landlord's. I solved it myself. The method is as follows, and the pro-test is effective:

1, open CAD.

2. Enter AP and press enter.

3. Search the scope to find the Ivy installation folder (note: it is not the source file), and the name should be YLTool.

4. Load all the contents in the file, and cad will automatically leave some useful contents for your own version.

5. Start some content in the group and add only a few useful content, otherwise it may be a bit annoying. Can be packed one by one, but not many, close.

6, restart CAD, you're done, pure manual.

7. Share for the first time. Give me a compliment.
