Cumulus Support

I am experiencing several problem so I was wondering how uninstall CumulusMX before to reinstall the correct mono version and repeat CumulusMX installation
Here there are some information about my configuration

sudo mono /home/pi/CumulusMX/CumulusMX.exe

Maybe and then ?

reading the error it appears you do not have a MXdiags directory. You might try creating one first.

the MXdiags directory alreay exists, this is the reason I would uninstall everything and make a new installation of mono+CumulusMX

It's as Roger says,you aren't following the instructions and changing to the Cumulus directory.

I enter and then and everything is Ok
