Won't Finish Instalation

I can’t finish the installation on my Windows 10. It prepares to install in the InstallShield Wizard. It says: Toon Boom Harmony 15.0 Premium Setup is preparing the InstallShield Wizard, which will guide you through the program setup process. Then loads for about 5 mins. Then when it’s ready, I click next and accept the license agreement, select the folder to store it in, select Complete installation (I tried Standalone too). It makes sure I’ve reviewed my installation settings, I click Install then an error message pops up saying: Error 1500.Another installation is in progress. You must complete that installation before continuing this one. I don’t have anything else installing on my computer, what do I do?

I am having this same issue, has there been a fix yet?
