I am having a problem with Sony Vegas Pro 8 as i start it i get this error (shown in the picture) This as been very frustrating and i have looked around i have found people with a similar error and i have done what the reply said but this didn't seem to work
This is what they said to do - THIS DID NOT! WORK FOR ME -
"Go to system properties and advanced system settings then where it says performance click on that and then on the Data Execution Prevention tab, make sure "turn on dep for all programs and services except those I select" is on and click on add which will then let you browse around, browse to the Sony folder in the program files and find the vegas80.exe file and add that and apply, that's it. Start up Vegas and see what happens."
Please help
