Snowleopard: About incompatible software
Software restricted during installation and migration
During installation, Snow Leopard moves known-incompatible software to a folder named Incompatible Software at the root level of the hard drive. If you see this folder on your Mac, use the table below to check with the software vendor to see if any Mac OS X v10.6 Snow Leopard-compatible updates are available.
None of my software is on this list.
