安装 auto cad 时 出现Failed Installation aborted, Result=1603 错误 安装不了 怎么办

可能是你之前装过其它版本的CAD没有卸载干净

换张盗版光盘再试

Error 1603 during software installation
Your Autodesk software installation failed and you found the following error in the setup logs:
Install AutoCAD Failed Installation aborted, Result=1603
Error 1603 indicates there was a failure during the installation, but in most cases this error message is not useful for providing an accurate diagnosis of the installation problem.
If you are seeing this error after attempting a silent installation from a network deployment, you should refer to the following instructions:
Use the Deployment Wizard (AutoCAD 2007 and older versions) or the Modify link located in the deployment folder (AutoCAD 2008 and newer versions) to modify your deployment.
Clear the Client Installations Will Be Run in Silent Mode option.
Complete the Deployment Wizard.
Run the client installation again and note any error messages that are displayed.
以上为AUTODESK官网关于错误1603的解决方法，囧。方法为1.彻底清理旧版本再安装2.重装最新版本的WIZARD
最有效的方法是，重新找个可靠的版本安装，你的CAD安装版本有问题的可能性非常大。
