Hi, I'm running "Movie Studio 17 Platinum" on a Dell 5530 laptop with Windows 10.
The full error message reads: The Device 'Microsoft DV Camera and VCR' Could Not Be Opened. Please make sure that it is turned on and is not being used by another application or user.
The camera is a Sony DCR-TRV840 connected via Firewire. Device manager says it is working correctly. Studio 17 recognizes the camera as "Microsoft DV Camera and VCR" which makes the driver suspect. I went to Sony's web site but no driver for USBDRVEN.EXE found for Windows 10.
The Camera's A/V DV Out is turned ON. It works fine on my ancient Windows XP machine with an ancient version of Adobe Premier. There is no software control or playback interactivity with the camera.
I checked everything in the FAQ ( https://www.vegascreativesoftware.info/us/support/article/capturing-video-from-a-sony-camcorder--222/)
Rebooted several times since I just installed Movie Studio. Nothing helps.
Any help appreciated
