Hi.
I've got a KT with serial B011, fw 5.1.2 in spanish. First I installed version 1.0.1 of the Launcher (the link is in the first post) but it didn't work (maybe updating that link to later versions should be great to avoid this happens again). I read on until I found the latter update of the Launcher (1.2.2).
To be a "good boy" I executed the uninstall for the 1.0.1 version and later tried to install version 1.2.2. It returned a ERROR 3 and didn't worked. I deleted by hand the "extensions" directory and tried to install again. This time it worked OK.
to everyone who spent time developing, documenting and testing this software.
regards
