SOFTWARE DOWNLOAD
Download Check-List:
Do you need the last version?
It is recommended to use the latest version for which your license is valid. Before you download, please consult the CT&A Revision
History page or the PatchTool Revision History page.
Is your license valid for the latest version?
A license remains valid for all incremental updates within a version number. For example, a license remains valid between versions 6.5
and 6.6 but not between versions 6.x and 7.x. Without a valid license, the program will run in demo mode.
Should you keep the old version?
You should NOT install two versions of PatchTool or two versions of CT&A on the same computer. First deactivate (if the licensing was
based on an activated Key), then uninstall the older or unwanted version before installing the software. We strongly recommend that
you keep a backup of ALL your install files (the downloaded setup file in Windows and the downloaded disk image for Mac). For the
macOS CT&A version, you should also keep a backup of your Color Deck database, located in the application folder, if you added one or
more decks.
