I love Install Manager and don't want to use anything else. I've never had any problems with it. Although there are people who definitely handle it differently. I'm thinking of eelgoo right now.
Hello, it depends on which version you want to install. DAZ will only offer you the latest version (4.24). I haven't tried it, but I read some concerning posts about it on the official forums, so I decided to stick to 4.23. If you want a previous version you'll need to find an installer.
