[Alan Murdock] "I downloaded and installed it, but it's also not working. Is it possible the install, which was part of the Imagination Studio Viao Edition, is only a trial?"
Because your original post said, "
I've been trying to get my Sony Vegas 11 to render." everyone here thinks you are running Vegas Pro 11. You are not. You are running Sony Movie Studio 11 which only comes in 32-bit (there is no 64-bit version).
[Alan Murdock] "I updated all of the dll files recommended by many to indicate it can use more than 2gigs of ram, I adjusted the render template to "render using GPU if available.""
You should NOT be changing DLL's and then complaining when things don't work. If Movie Studio was meant to use more that 2GB of memory, I'm sure the developers at Sony would have compiled it to be Large Address Aware but they did not. Once you go changing DLL's there is no telling what damage you have done.
[Alan Murdock] "Is the software not recognizing my video card? I'm editing HD video on a Sony Vaio laptop with Intel Core i5-2450M CPU @ 2.50gHz 6GB ram 64-bit video processor is Intel HD Graphics 3000"
No the software will not recognise your video card because built-in Intel HD Graphics is not supported. You need a separate video card that supports NVIDIA CUDA or OpenCL.
[Alan Murdock] "When I first got the computer last month I was able to render one four-minute video twice."
If the software worked a month ago, and you don't have a backup from a month ago, I would recommend that you find the system restore disk that came with your computer and restore it to it's original condition. Then don't play with the DLL files anymore and everything should be fine.
If you want a 64-bit version of Movie Studio you can upgrade to Movie Studio Platinum 12 which supports 64-bit. You probably qualify for the $64.95 USD upgrade price.
