Bones.... Let's logically step thru this.

Does this happen w/ other apps, specifically apps that require graphic acceleration.

Verify that your version of Vegas 12 is not corrupted. If you haven't already, re-download. Remove and reinstall Vegas 12.

Try installing Vegas 12 on another machine. If it loads and works fine then it may be the hardware.

You may have memory issues. Try re-seating your RAM.

Do a mem test and see if there are errors. If the memory is good you may want to check your video card. I've had cases where the card was DOA and though it could run basic apps when I loaded a game or anything that would require graphic acceleration would crash.

If you know the card and ram are good, re-check the CPU is seated correctly and the heat sink is secured properly. I've had issues w/ mis-aligned heat sink causing the CPU to overheat even though the cooler was nice and cool. I cant recall if the 3770 has pins but verify the pins are not bent on the CPU or socket, Yes, I've bent a pin or 2 in my day, fortunately I was able to use a pair of fine needle nose pliers an un-unbend them and save my CPU! (:

I used to run Vegas 12 Pro on an i7 quad core (now using a hex core) and many here are using quad cores so there may be a deeper issue than Vegas 12 here.

Does it show as running in the Windows Task Manager (CTRL+ALT+DEL)? Does it show in the Taskbar? If yes, the window may have just gotten moved off screen into no mans land.

Assuming all of the above are true, you can try this to restore it. Do an ALT+Tab until Vegas is active or click on it in the taskbar. Press ALT+Space. Now these you have to do blind.

Down arrow once then Enter.
Now try using the arrow keys to pull the window back into view. Once you can see the cross cursor and the Vegas title bar, move it to where you want and Enter.

This is just a thought as I had something similar a few years ago. I don't remember if it was Vegas specifically or not. However, the app gave all indications that it should be running but was nowhere to be found and otherwise inaccessible. The above steps fixed my issue.

1. All software licensed.

2. Only thing changed was CPU from Sandy to Ivy Bridge.

3. I do think the problem started BEFORE the CPU upgrade but can't be 100% sure.

4. Vegas does not start at all. Didn't work in safe mode. Didn't work launching as admin. Does not appear in the task manager as running. It doesn't appear even in working processes.

5. I don't need to test the software in another computer. I'm sure it works. Redownloading and reinstalling didn't work. It doesn't launch at all.

I've seen others have this problem with no solution. I've also heard that if any type of acceleration may have been on, you need to turn it off. But if that was the case (a) there should be a warning message which there isn't; and (b) there is no way to turn off what you can't access any more at this point.

6. No other apps have a problem. I ended up using a competing video software which is actually nicer than I thought. Works very smoothly. The problem is not the RAM or the CPU or the computer. I've checked them all too, including virus, hard disks, RAM, etc.

20% boost? That spells trouble in my opinion. Those new processors also have a slew of new functions added that require new motherboard drivers. But since I am not a guru you can take this with a grain of salt.

The i7-3770K is not "new" processor by any means. It's just a top of the line Ivy Bridge instead of a middle of the line Sandy Bridge and supplies Intel HD 4000 graphics too. This is standard and everything else works. It's definitely Vegas, not the computer or the CPU. As I mentioned, someone suggested that the problem is in Vegas and a setting that can't be adjusted, e.g. the GPU Acceleration bug that others complained about. Might be it but it has taken me down for the count.

Vegas registration has a unique machine ID that is hardware-bound.
Contact Customer Service, not Technical Support.

I have swapped the motherboard and CPU from under Vegas 12 in a given machine. It just needed to be re-activated since the hardware was changed.

My only thought is to try starting Vegas will ctrl+shift are held down and reset Vegas to default preferences and check the option for Vegas to delete all stored data. Or just plain zap, the Vegas "appdata" folder yourself.

Thanks. Vegas 12 is hosed. Started using another product because I have a project due and can't screw around any longer with this... crazy.

- Deinstalled.
- Renamed folders - programs, appdata (local and roaming)

Still nothing. Click, does nothing. Something is hidden somewhere and simply will not allow Vegas 12 to launch.

And you did reinstall your OS ??

What OS?

Check the various system logs. There may be an error in the logs that points you to a service that is not starting or a device driver that is not loading correctly.
