The error message states you do not have administrative privileges to delete the VSTSynthfont64 file. That is a Windows, not Band-in-a-Box, error message. Windows thinks you are not signed into Windows as an Administrator. You will likely run into a similar error message each time you try to delete some files.

For Windows 10 you can navigate to Windows Security > Account Protection > View Your Account info to verify if you're signed into Windows as Administrator.
