My SSD is formatted case sensitive, so when I attempted to install I got this:

Installation on case sensitive volumes isn't allowed. Please choose a case insensitive location.

But I can't select the install location.

Why is your internal drive formatted case-sensitive? Is there some specific reason this is the case? It's generally considered a bad idea to do that for precisely this reason: you won't be able to install some software. – CajunLuke Aug 22 '12 at 20:47
See… for list of programs and possible solutions to HSFX (case-sensitive) filesystems. – user588 Aug 22 '12 at 23:57
@CajunLuke When I bought my SSD I thought that I will have some benefits by formating to case-sensitive. But later I realized that not really. Not even the big guns like Blizard or Adobe pay attention to these benfits... Maybe 3 years later :) – Boti Aug 23 '12 at 6:56
I also tried to specify the location to be a case insensitive external drive to the downloader but when the installer finally has downloaded then the result was the same... I would consider this a small bug from Adobe (they are checking the filesystem of the main drive not the filesystem of the target location). So I have no other choice than to convert my drive to a less intelligent file system... Those software developers... they always leave some small bugs behind them :) – Boti Aug 23 '12 at 7:07
@Boti You're not the only one. I formatted one of my Macs HFS+ case-sensitive once in college and had a helluva time getting anything to work. I fail to understand why they even leave the option in Disk Utility, as it's of limited utility and just confuses people. – CajunLuke Aug 23 '12 at 14:35

Not the answer you want, but whatever.

Re-format your SSD to the default of HFS+ case-insensitive. Almost all Mac software is designed to run on a case-insensitive file system and you using case sensitivity is the problem.

Maybe you'll find a solution here.
