My android is 4.0.3 and is on an Acer Iconia Tablet A100. I have rooted it already using this process, and the rooting persists between reboots. I can confirm root access with the Root Checker app.
I have installed the Android SDK and it's required Java SDK.
When I run Droid Explorer I get this message:
What do I do?

/system/appjust fine - it list all the contents. I wanted DroidExplorer in the first place just to try it's Full Backup Feature, hoping it would back up the entire device to my computer's hdd; I tried it, but I'm not sure what it did, exactly. Oh neat! The screen monitor works! – bgmCoder Nov 02 '15 at 04:53
