--- Comment #9 from Emmet O'Neill emmetoneill.pdx@gmail.com --- (By the way, another workaround is to go to the IK Multimedia website and then to "My Products > [PRODUCT] > Past Releases", where you can find direct downloads to zip archives of some versions of each product, and then manually run the installer in the same prefix as your IK Product Manager. This method does not require a Windows machine at all, though its not as convenient or up-to-date as going through the product manager software.)
