I just purchased an upgrade to Vegas Pro 17 (currently using Movie Studio Platinum 16), and I'm trying to install it on Windows 10 64-bit. I have plenty of storage space and memory. I have tried repeatedly, including following a system reboot and including running the installer as administrator, and the behavior is consistently as follows:
1) I execute the downloaded installer (Build 421). (Note: I also re-downloaded the installer, but the downloaded files are identical in size, and the behavior described here is the same.)
2) I choose the language for installation, accept the license agreement, and specify a destination folder.
3) The installer starts and gets to the point where it says "Preparing to install Vegas Pro 17"; the progress bar is less than half-complete when the installation dialog closes and a confirmation dialog appears with the message "Vegas Pro 17.0 has been successfully installed." I click Finish.
Nothing actually gets installed. The destination folder is empty, and the list of installed programs in the Control Panel does not include Vegas.
Any help is much appreciated. Thanks.
