Moved the apk to system/app with RootExplorer and installed it after. But everytime I want to add a widget from the launcher, it says, I have to move it to system/app (root required)
I installed it now 2 times and rebootet my device 4 times.
My phone is running CM9 and I don´t know where the mistake is, because Nova Launcher were no problem...
You only have to move to /system/app, do not install the apk, just move it...
