安装时出现product code和upgrade code错误(100分)

用delphi自带的打包程序install shield limited edition制作打包文件，安装时出现错误：error 1406.could not write value versionminor to key/software/microsoft/windows/currentversion/uninstall/{4fa8a3c7-ba2c-40a6-a630-778442155150}.verify that you have sufficient access to that key,or contact your support personel.
一共两个错误，分别是product code和upgrade code。我在制作时已经将两者设为一致了，为什么会出现这种错误？怎么解决？
