I tried everything possible and searched the internet. Be it the ErrorReportClient rename or rausnehmen, up to the update of my graphics card (have a laptop)
I just know that older versions so Vegas Pro 11 or 12 did not work if you had Quicktime installed. For whatever reason…
Great reply…
Call the support, if you buy the license, then you can expect good support for it!
