The withholding end of downloading the natural person electronic tax bureau shows that you have installed this product, and you cannot install Hello Dear. This product may have been installed before, but it was not completely uninstalled. Or the installation is not complete, but it is in the registry. You must uninstall it, that is, delete it from the registry before installing it. So you must find this software from Add and Remove Programs. Delete. You should check it first.
