我的bcb6是企业版，而且以前升级成功。重装了系统之后，给bcb6升级就不行了。 setup is not able to determine the product edition that was installed.it does not appear that the update you are trying to apply matches the edition that is installed.product edition information in the registry or binary files may also be corrupt.if you are sure that this update is correct for the edition you have installed you may need to re-install your product. 把bcb6卸了两遍，又重装了两遍。还是不管用！！！ 努力学习
