Amcap is/was a Microsoft product. there are indistinguishable rip-offs out there under the name 'CamApp'.
If you want a totally flexible camera control program use the excellent Sharpcap, it's meant for astronomy but that just means extra features, it works for any camera and will take stills, capture sequences of videos at intervals from seconds to hours etc. and automatically accesses any special features of your camera such as zoom, capture rates., different codecs…
One thing you will need to do (and it sounds like you haven't done as it won't work in movie maker) is get the right driver for your camera. Find it in device manager and look at its properties, if you can identify the product number of the camera then googling that plus 'driver' will help – but beware some driver sites are virus traps. Sorry if that confuses rather than helps…
