While trying to install Sony Vegas Movie Studio Platinum 8.0 on a new computer I received the following Error 12037 - the date in the certificate is invalid or has expired. How do I reinstall the software on a new laptop - Microsoft Windows 10
I wonder if this may apply: "Older versions of Vegas Pro than 14.0 are licensed under a system (as previously used by Sony) which permits use on multiple computers by one user; after an unspecified number of installations on different or updated PCs you may need to contact support to reset your "installation count"."

Greg, why to reinstall that if for $25 you can jump 10 versions up, to VP18?
