Did you migrate or copy the files when you installed InDesign? Or did you install from a backup?
That won't work. You must install either from the original media (if you bought it on disc) or from a download installer.
If you did that, you'll also have to clean up the install with Adobe Cleaner Tool:
Here's a link for downloading CS5.5 software:
Also, CS5.5 is not officially supported on Mavericks or Yosemite the newest versions of Mac OS X. It might work, it might not.
Sorry for my late answer. Thanks alot. Yes I transfered the whole content from my old mac to the new but the others programs have been working. Well not flawless but still.
I have the retina-screen and all the adobe programs have a lower resolution so it looks "pixely" in the menus and so on.
Do I have to do any changes to the old programs that work or can I just keep using them and only install indesign from the master collection file?
Oh I saw now that you wrote that the cs5.5 is not supported by Yosemite. Is there a way to buy the latest version like I did before without the subrice-version?
I would recommend only to subscribe as CS6 has reached EOL (End of Life) and will not support future OS. Buying CS6 will cause you encounter the same problem very soon again.
Not supported doesn't necessarily mean it won't run, just that you may have some issues. Before you throw a lot of money at another version that does not have Retina display support (InDesign does not have support for Retina until CC), you really should uninstall the Adobe programs, run the cleaner tool (CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3) and try reinstalling CS5.5 from the original installer.
FWIW, The CS6 versions of Photoshop and Illustrator do support retina displays, but InDesign CS6 does not and it is beginning to show O/S incompatibilities. Spending money on that upgrade would be throwing good money after bad.
Thanks everyone. I got good tips from everyone of you..
I will probably start to subribe to cc since I work with this programs everyday.
It is still a lot of money though for a "little" company like mine. But I really need them to work flawlessly.
Super big thanks to you all!
