For all users who are experiencing Vegas start up issues, the culprit is a recent Windows 11 update. Thus installing this new version: https://rdir.magix.net/?page=LXXNHP3P4WG3 should have your issues resolved.
The new version is for Vegas Pro 20, what about those of us with Vegas 19? Do we get a free upgrade? I am not paying another dime for software that runs like crap constantly. I have already started projects as of yesterday, May 3, 2023 that I can not access now because Vegas won't open...no Windows update between yesterday and today. FYI, this is on 2 computers same issue. Uninstalled and reinstalled Vegas 19, opened fine but of course can not open new project in old install, did update and back to not opening. This is not a Windows issue, it's a Vegas issue someplace.
@RogerS I did find the VP19 Download, thank you for the FYI. We shouldn't have to hunt for this? Magix should just email us with a big fat apology and the link attached. Glad I have purchased Davinci Resolve. I have 2 projects to complete in VP19 then I will struggle with learning DR for all my future editing.
I can confirm... neither Vegas 19 build 648 nor Vegas 20 build 402 will load this morning with Internet access enabled on my 2 win10 machines as well as my 2 running win11. Turning off Internet access temporarily till the Vegas screen pops up fixes them all. I imagine this will only work till Vegas needs to call home during load for a license check. Vegas 19 update/download keeps failing so I haven't been able to try that.
