Help please,

Tried opening Vegas 12 today (previous build) and it failed. The advice was to upgrade to fix the problem so installed build 710.

Now it wont open with the following fault report:

Problem Description
Application Name: Vegas Pro
Application Version: Version 12.0 (Build 710) 64-bit

I have no idea what is going on here but the splash screen hangs at:
Initializing GPU-accelerated video processing...

My AMD graphics card does not support GPU rendering so I don't know if it's trying to start up with it enabled.
Is there a safe mode startup for Vegas that I can make sure the function is disabled please anyone?

p.s. I also have Vegas v10 on the workstation and that opens fine.

Sounds frustrating. I hope you can fix this troublesome issue.

The advice handed out in situations like yours Steve is always install the latest upgrade to fix things, but often it will not fix much of anything, aside from specific issues the upgrade is supposed to fix.

When you can't start up you likely have some kind of software or hardware conflict. If you're using an OEM machine, an reinstall from scratch of your OS may or may not fix things, but you could try it.

Short of that, you could try uninstalling your video driver and updating it, if it's not the latest, and see what happens. If you have another video card to swap out try that and see what happens, uninstalling your old driver first. Good luck.

Steve, have you integrated video card on m/b? Try remove ATI and set on onboard card.

I was just shown this possible fix today:

1. Go to the Control Panel/Programs & Features
2. Right-click the "AMD Catalyst Manager" and pick "Change" on the pop-up menu
3. Click on Next
4. Choose "Uninstall" and click on Next
5. Choose "Custom" and click on Next
6. Choose "AMD APP SDK Runtime" and click on Next"

Build 12.0.710 is removed now from SCS

Steve, go to system restore, and restore to an earlier point (before the 710 upgrade). It's the easiest way to roll back to the previous version, and it won't affect your other files.

Build 12.0.710 is removed now from SCS

Juris, 12 build 714 is now available for download. Will try an update tomorrow.

It works ;)

I just upgraded on to 714 on my laptop and now I don't see any images on the video preview window. I can see thumbnails on the timeline and see and hear audio waveforms but no video, nor will it export the video just a black screen. I tried reinstalling QT but that didn't seem to work. Ideas?

Here's my escalating methods for an install/repair:

Primary:Factory Reset: Hold Ctrl+Shift while booting up Vegas. This will force Vegas to perform a Default. Fire-up VP.

Not good? Then:-

Secondary: Reinstall - First reboot and then reinstall and after reboot. Fire-up VP

Not good? Then:-

Thirdly: Uninstall and then reinstall - First reboot, uninstall, reboot and then reinstall and after that reboot. Fire-up VP.

Not good? Then:-

Fourth: Re-download s/w Try again.

HTHs

Grazie

Thanks I'll give it a try.
