Windows or Mac, and exactly which operating system version?
Are you running your computer using an Administrator account?
I just talked to Support and they walked me through the solution. It has to do with the permissions of two folders. Fix these and then try it.
Click on Go in Finder.
GO to folder
Type ~/Library & hit return.
Open caches folder
Select Indesign over there.
Click on the lock icon & unlock it.
Now, click on + sign & add your user name out there.
Now, give the permission as Read & write by selecting the drop down all mentioned users there.
Now, click on gear icon in bottom & choose option apply to enclosed items.
Save the changes & lock it again.
Now, open the preferences folder in user library.
Select Adobe Indesign folder here as well.
Do the same thing
I'm having the same problem but I'm on windows 10??
