If your video resolution is set to 640 x 480 then you
will have this problem on the older versions of MultiCam. You can either upgrade the software to the latest version or do the following
steps to fix.
1) Configure --> Video Source Change the Video Resolution to
the one higher than 320 x 240 on V6.1 and below 640x240 on V7.04
2) Configure --> Camera/ Audio Install Now, Audio and Wave
out are no longer grayed out.
