Can't install on HTC Tattoo

as you planned to bugfix this issue with htc tattoo i cannot see you did. whenever i tried to upgrade from droidlive to xiialive several times now, i always got things wrong. after i downloaded the app it won't install correctly, a text appears saying "...can not be installed on this device." no reason given, no try succeeded so far. any ideas? please, respond to the given email address. as i am natively speaking german, please try to keep your english somewhat simple. thanks in advance, alex from germany

Hi Alex, have you tried uninstalling and than turning off the phone.  Turn phone on and try installing.  Let me know if this fails.  This seems to be more of an issue with Android OS than it does with the app.
