Installation Steps
In all cases, use the setup.exe program on the product CD or in the web package if you downloaded it.
The setup program automates the Plug and Play steps needed to install the drivers and ensures they are
performed correctly. It also installs the bundled applets and User’s Guide. If you have multiple Osprey
capture cards in the system it configures all of the boards at the same time.
We recommend this method especially if Osprey software does reside on your host computer. After the
install is run, the software detects the card and its drivers initiate automatically.
If you are updating Osprey software, first uninstall the previous software version, reboot your computer,
and then install the update.
Installing the driver
Insert the Osprey Software CD into your CD-Rom drive. The main menu for the Osprey software appears
if you enable autoplay. If the main menu does not automatically appear, click on the Window’s
computer icon and select the CD-Rom and the setup.exe icon. The Osprey A/VStream –Install Shield
Wizard engages and guides you through the installation process.
Installation Steps

Custom installing AVStream
During the installation process, if you choose a Custom installation, your options are limited (Figure 1).
Figure 1. Osprey 240e Custom Setup screen
This window allows you to choose individual components you may want to install. You can also change
the location where components install.
Installing the video capture card
This manual covers one class of Osprey devices that include two PCI Express cards.
Class 6: o-240e, o-450e and related non-DSP PCI Express products
Both cards use the same driver. If you add a card from a different class, then you need to install the
driver for that card.
When you add or move boards after the AVStream 4.6 driver is already installed, there are two
possibilities:
You add a board of a different class from what is already in the machine. For example, an
Osprey 240e is already in the machine with the current driver installed, and you want to add
an Osprey 530. For this case, you have to obtain and install the driver install package for the
new board.
You move a board from one slot to another, or if you add another board of the same type.
For example, you might have an Osprey 240e in the machine, and want to add another
Osprey 240e. In this case, the following sequence begins.
