# Upgrading to QPix v2.2x

When upgrading to QPix v2.2x from v2.0x or v2.1x, please keep in mind the following:

Upgrade to QuickTime 5

QPix v2.2x may run also with earlier versions of QuickTime, but a full installation of QT5 is recommended. For a full installation of QuickTime, choose the Custom installation in the QuickTime installer, then select all available components.

Use 4D 6.0, 6.5, 6.7 or 6.8

4D v3 (vf5) is not supported; you must use 4D v6.06 or later. If you are under MacOS X you must use 4D 6.8 (it's the only Carbon 4D).

Do not use 68K Macs

Old Macintoshes based on the 68K processor architecture are not supported; your Mac has to be PowerPC-based.

Changes in license registration

QPix v2.2x uses a new registration procedure.

License codes issued for QPix v2.0x and v2.1x will still work for QPix v2.2x, but the QPx_Register command has become obsolete. Therefore you must register your license keys in the new registration dialogs. More on adding and removing license keys...
