thanks for your answer. After reading your linked themes, i tried the following things.
- installing java 7 update latest instead of java 8 => now result
- then i deleted all the adobe folders in ~/Library/Application Support/ and /Library/Application Support/. Also i deleted all adobe programms in the Ulilities and java. After a reboot of the mac i installed CC Cloud. = now result
- installing java 8 again => now result
- After all these operations i installed flash ad air again.
When i rund the CC desktop application i can see the grea icon in the menubar for two seconds or so an then it disapears.
I don't have an idea what i can do next.
So i can't testing photoshop and lightroom now.
Now i found out, with logging in to the root account, i can use cc desktop an install apps. Going back to admin account i can use the programs. So i thing there is a problem with the rights in the admin account using cc desktop, but i don't know what i have to change.
This is a workaround not a solution for the Problem.
Now i found a way to solve my problem.
I activated a new administration account. As i looked in an old internet plugin called cooliris wasn't able to start. => cc desktop had problems.
So i looked for a way to uninstall it. => After a new login cc desktop worked very well.
I changed to my normal user account. There i put all internet plugins in a separate directory. => cc desktop was working.
After moving all internet plugins back to the original location cc desktop still worked. After a restart of the mac cc desktop also had no problems.
So now you can close this post. I hope this solution can help other users.
