Chapter index | Step: 1 - 2 - 3 - 4 - 5 - 6

# Step 1: Install QuickTime, register QPix

QPix requires a full installation of the latest version of QuickTime. While still editing the On Startup database method, we should check the currently installed QuickTime version.

The code snippet below informs the user and quits 4D if a version earlier than 5 is installed:

``Check QuickTime version` `C_STRING``(63;$QTVersion)` `$error:=QPx_GetQuickTimeVersion($QTVersion)` `If``(Num(Substring($QTVersion;5))<Num("0500"))` `ALERT``("QuickTime 5 or later is not installed!";"Quit")` `QUIT 4D` `End if`

To use QPix without the 30-minute evaluation limit, first buy a Developer license for your development platform, and install the license key that you will get in your database by following the license key installation instructions.
