Ardu may be a shortening of the word Arduino and used to indicate that the original Ardupilot used an Arduino Atmel processor, the 168/328.

Is Ardu an acronym?  I feel it must be, but can't find anything to explain it.  I just know I'll be sorry for asking this.

They change the folder from "APM Planner" to the new folder "Mission Planner". I have the same errors when I did the upgrade. More than that, all my cash maps are not more working even I do copy the cash map folder from one location to other.

At least we should be informed about those modification.

Oooppsss! "ArdupilotMegaPlanner10.exe"

Upgrade errors out? 1.2.81? Well, the startup problem for .81 is that they changed the name of the startup application and missed a link somewhere. That is what the indication is to me. And how I found the fix. If you look into the application folder there are two applications: "ArdupilotPlanner10.exe" and "MissionPlanner.exe".

The old version was and is linked to the application icon as "ArdupilotMegaPlanner10.exe" some where the change went to "MissionPlanner.exe" and the link/pointer was not changed for the installed application icon.

Right click on the Mission Planner icon you normally use and select 'Properties'. Now change the application name from "ArdupilotMegaPlanner10.exe" to "MissionPlanner.exe" - Click on 'Apply'. Now, the application should work. It does for my instance.

You can also grab .81 and install fresh from there..
