Installing Software on External HD

[BenMurrie]

Hi there
I just want to install EWQL Symphonic Orchestras on my 2TB hard drive, but it does not allow me to. I can only install it on my internal mac HD. What can I do to allow the installation on the external HD?
Thanks

If the installer comes in the form of a package (.pkg) file, you could try opening it up with Pacifist and manually installing elsewhere. However, if there's anything that has to go into /Library or ~/Library, that won't be able to be placed on a non-system drive.
