The steps to install MediaRecorder
IMPORTANT
If you have an older version of MediaRecorder - Uninstall MediaRecorder 6.0 and older versions before you install MediaRecorder 6.5.
If you have a hardware key - Do not insert your key before the installation is complete. If you do so, other drivers are automatically installed, which may lead to incorrect functioning of the license key. Drivers of the license key should be installed using the installation USB stick.
