Complete uninstallation of Corel2018 trial version

When I install commercial v2018 on a PC where it was previously trial, setup normally starts the installation. When about 50% occurs, it throws a message that a newer version is installed on this pc and continues to click OK. At the end, he writes info about installing Visual C 2017 libraries, and then immediately the setup ends with a message about incomplete and fatal error. I removed normally the trial before, restarted the PC. What can you do about it? Is there any Corel cleaner installation in general? Did anyone meet that? I don't know what to do with it.
Thanks for the possible reaction.
