Camera OK, Software disaster

I wanted to have a compact camera for the holidays, with a large zoom range and good video function.
At the end remained (like many others) only Panasonic and Sony left.
Because Sony was beset in hand, I decided for them.
Photos also okay, processing well (the lid from the battery compartment dissolves ever more frequently, the lens looks a bit shaky). Can I live but all in all, with,

What does not go on and the camera software.
To further complicate matters does not go well, what ???
Attempts since 3 hours !!! to transfer the app "lapse" for proud 9.99 on the camera.
Not possible. Or I'm too stupid ...
Again register somewhere at Sony, in the tangle of additional products for television, Playstation, mobile phones etc. are to be somewhere Apps for the camera. Found, camera is not recognized. Aha. Should something to install, I also behaved. Still does not work ... What is the reason also, I have no way to expand the camera functions.
and which are sown in the Sony from scratch rather sparse ...

Too bad, am going to have to look what else.
