Hello,
Today I decided to try again Trend Micro Maximum Security, but the installation fails with the error message: "interrupted-reason_Instal12"
I have tried to run the "uninstall tool" and the "permission tool".
Install.12 is an installation that extracts the files but does not install them. The first thing to check would be permissions as far as right clicking the installer and running it as administrator.
Have you tried to back everything up and perform a clean install of windows? Also TrendMicro support may be able to help you. They do have a live support Channell.
