Adobe allows you to transfer your copy of Acrobat to any computer in your business, as long as you also transfer your license and activation. If you don't have an installation CD you can download the software to the new computer, but only if you purchased Acrobat directly from Adobe. If you're using the latest version of Acrobat, you can also download and activate the trial version of Adobe using your existing license; otherwise, you won't be able to transfer Acrobat unless you can get the installation file from another source.
