Get the version of QuickTime
Parameter versionString receives the version of QuickTime running on your machine. The encoded string value that expresses the QuickTime version number is constructed as follows:
| Characters | Description |
|---|---|
| 1 | F = final, B = beta, A = alpha, D = development |
| 2-3-4 | Internal number |
| 5-6 | Version number |
| 7 | Update number |
| 8 | Revision number |
For example, the string "F0000403" stands for the Final release of version 4.0.3.
If QuickTime is not installed, an error code is returned and versionString is set to empty.
