Hello again- Now I am trying to reinstall version 1.4.4.4. I run the installer for it that I downloaded & almost immediately after I run it, I get a message that version 2.5.1.0 is already installed & must remove it before installing version 1.4.4.4. I did remove it from programs & features & from Computer Program Files. What must I do and/ or is there an uninstaller for it?
