Install problems

I have tried to install Edge Animate CC a couple of times now and the same thing happens.

The installation starts and the progress bar goes to 50%.

Then a window pups up and say the following (I run Creative Cloud in norwegian so my translation to eng. might be a bit off, sorry):

Close the following program to continue:

- Edge Animate (Adobe Edge Animate)

and it gives me two choices:

try again and close.

try again just gives me the same error.

I run a brand new 27" Imac with:

OS X 10.8.4

3.2 GHz i5

8 Gb ram

NVIDIA GeForce GTX 675MX 1024 MB

Any ideas how to fix this?
