When you try to install an Adobe product, you receive the message, "Case-sensitive drives not supported" in the Install Options panel. Or, you receive an error message such as the following:

File system of setup volume not supported.
This software cannot be installed because the file system of the OS volume is not supported.
Unsupported OS version
Unsupported filesystem on system disk

Install the product onto an HFS+ or HFSJ non-case-sensitive drive.

Adobe products cannot be installed onto a volume that uses a case-sensitive file system, such as HSFX (HFS+) or UFS. This limitation applies to both the startup drive as well as the drive onto which the software is installed.
