Few questions about installing the Device Manager 4.5......
Should I remove the old program from my computer before I install the 4.5, or does it matter either way?
Next, I have the Device Manager on my desktop and the English service books w/media player on my desktop ready to open. Do I have to open/install them in order, or does that matter?
I suggest you stick with 4.3 for now. Slow sync speeds have been reported with 4.5. There's nothing really good/new in DM4.5 anyway. It's the OS that's important, not DM.
However, yes, you'd need to uninstall the old version before installing the new version... to keep things clean.
