I have been using Movie Studio, various versions, for 16 years. Currently Movie Studio 16.0 Platinum. I have. A completed project that will not render audio (Ac3). The problem started when I downloaded Windows 11 and it rendered my PC useless. I was previously using Windows 10. I purchased a new PC (Dell) with Windows 10 installed. This is when the audio would not render. The person I purchased the new PC from (25 years experience) insists it is not the problem. However, before Windows 11 on my old PC everything was working well. Could it be a compatible problem between the PC and Movie Studio? These are the error messages I receive; “The selected encode format requires the download of an add-on software module the first time the format is used. If you wish to proceed ensure your PC is connected to the internet, then click Yes”. After clicking Yes I receive the following message; “Operational error - Installation failed, code: -1. On some systems this problem can be avoided by starting the application with the Windows “Run as Administrator” option then rendering the project again. After the component has downloaded successfully, the application can be closed and restarted normally, without the “Run as Administrator” option”.

I have tried the above suggestion several times without success.

Thank you
