I can't install USB driver for Sony handycam TRV250E

You can only install USB driver into a compatible operating system.
So therefore try and install the driver into a Operating system version support by your devices.
Or you check sony support online through google to download driver for your type of Operating system if available.
Best regards.

Hello, I too use the same camera, the driver for your camera is now free for download on the net to work with Win 7 okay? all you need do it connect your movie camera to the firewire prot on PC (NOT USB) and into the camera it goes into a tiny little plug like a D shape.
Once you have camera connected to PC then turn PC on and your PC finds your camera right away once booted uo.

If you download your movies to the PC you need a Firewire cable, USB often only works with Win XP, sorry the cable is around £14.

get another cheap pc with xp

win vista and win 7doesn't support usb streaming. the usb driver for this model would not be compatible with your computer's OS. although, you were able to download PMB still this wouldn't work, it's basically an alternative software that you can use with the newer OS. still the device driver would not be installed. and you would get a message that "ilink connection is not detected". the reason you get that is bec the camcorder and the software is intended for use with the dv (ilink or ieee1394) connection. so if your computer has an ieee1394 card and you have a compatible ilink cable,then your good to go,it should be a plug-and-play connection (no drivers required). all you need then would be a video capturing software (like win moviemaker) to transfer videos from tape to PC. hope this helps. thanks :)

Please got to Menu of your camera and enable USB Stream function.
