• unable to install antivirus on microsoft windows 11 computer

    I recently renewed my antivirus subscription, only to discover that the antivirus software would not launch on my laptop (never had a problem before).  So, I uninstalled and attempted to reinstall the software.  I downloaded the installation software, opened it, gave permission for the program to run, and then waited while the program said it was decompressing the files for installation.  After decompression ended, nothing else happened.  No new window, just a blank screen, no program running.  So I found "trend micro installer" in the program data folder and attempted to run setup.exe.  After giving permission for the program to run, it fails to launch.  I have tried all the work arounds I could find in these forums for installation issues.  Please help.
