试试这个：我开始也是这样，用注册机也这样，后来上网查到这段说明，才成功。 说明： 注册码如下： Here is your JBuilder 6 license key. To complete product registration, follow these steps: 1. Start your Borland product. The Registration Wizard will appear. 2. Select “Have License Key”, then click Next. 3. From the Import License Key page, select Paste license key text. 4. Copy the contents of this email between (not including) BEGIN BLOCK and the first END BLOCK. 5. From the Import License Key page, click the Clipboard Paste button. 6. Click Next to proceed with the registration. 7. In case of multiple license keys, repeat steps 2 to 6 with the successive BEGIN - END blocks.

1、将以上的注册码导入
2、将CRACK目录下的trial.jar目录整个复制到<jbuilder>/path目录内完成解密!这个是企业版的解密，不知道对专业版好不好用：）
试试看吧。这个trial.jar只有5、6kb网上down下来的不知道有没有。
