I have tried reinstalling moss several times but every single time I go to run it I still get “can’t update, error 4”. I’ve tried restarting my PC as well and nothing seems to be working! Anyone have the same issue?
you are not able to download a moss.exe version , the fact you need it means you have an old one or get the x86 one while you run a x64 OS.
or you unblock Moss in your antivirus/firewall or you get directly the last version or x64 version from my site
