安装了个,测试版的BDS2006,请问我该怎么升级它阿,运行程序后,总会给出提示错误:The upgrade patch Can not be installed by the windows installer service because the program to be upgraded may be missing,or the upgrade patch may update different version of the program.Verify that the program to be upgraed exist on your computer and that you have the correct upgrade path。请问我该怎么办?
