I tried to clean my CS 5.5 programs because InDesign wouldn't open, it would just quit unexpectedly, but my Photoshop and Illustrator were fine. When I went to clean the programs after uninstalling them (like it says to when using the cleaner tool) they were not in the cleaner tool window because they are now uninstalled. So confused. Just want Indesign to work like my other programs. I am using a Mac Desktop btw.
Which Mac OS are you using?
OS El Capitan 10.11.4.
CS5.5 is not supported under El Capitan. I'm afraid you're on your own here.
That said, if there's a crash report, paste it to pastebin.com and give us a link. Someone might spot something that could help.
