After downloading latest version (Feb 2018) I cannot run it, because I am always requested to "Repair" the file and restart the PC. My installation is Vaio fully featured with Windows 10 (updated automatically). Thanks for your help.
I am very sorry for my mental insufficiency. You easily fix the problem if you click the button "uninstall" first. Then the following setup process is OK.
Normally you shouldn't need to uninstall.... but who knows why windows sometimes decides otherwise. Glad you figured it out!
