On the premise of confirming that there is no problem with the software, there are several points to pay attention to when installing the series version of "drawing sound and drawing shadow": First, some versions are required to be installed on the default C disk and path; Secondly, if the audio-visual series version has been installed in the system, and it has been recorded in the registry, if you want to reinstall it, you must completely uninstall the audio-visual version on the original hard disk, clean up the registry, and restart it after shutdown. How can I completely uninstall? You can use super rabbit, optimizer, Kingsoft Guardian and other software to "uninstall" instead of simply deleting. Third, after uninstalling, you should use the software mentioned above to do two tasks: one is to clean up the disk garbage, and the other is to clean up the registry (the above software has these functions) and then install it after restarting. Only in this way can we completely delete the information left by the original installation version of "painting sound and painting shadow" and install the new version smoothly. Third, it is best to turn off virus interception functions such as firewall before installation, otherwise some plug-ins such as Chinese programs will be mistaken for viruses and cannot be installed smoothly.
