Tried downloading lrtl 4 but message says not safe and cannot be verified by Windows either.thnks

Just agree to that message. It's just because I've not digitally signed the installer.

There isn't anything to agree. Windows say cannot be verified and Norton security analyzes and and say' not safe and has been removed.'

If you have software on your computer that just remove clean installers (I've thoroughy checked that) then there is not much I can do other then advise you to turn off that software and install. then you can turn it on again. It's not the first time those Norton products block software that's totally fine.

OK, thnks . The first time I downloaded lrtl 3 in March there was no blocking from Norton. Also no message from windows that said I didn't have permission to run the lrtl program. I'll try again today.
