You failed to include all the log, since you omitted the first lines which contained the software version number, which are helpful to us to know if you are running the latest version or not. And, you should never "copy" the log in a post but, instead, ZIP the file and use the "Attach" function to attach it to a post, so we can sure it's not altered by the forum software.
In your case, it seems the problem is caused by not having write access to the GSX Programdata folder, most likely caused by the antivirus. Try this:
- Restart Windows
- Remove the whole C:\ProgramData\Virtuali when the simulator is NOT running.
- Configure the antivirus to exclude the whole Addon Manager folder from scanning
- Run the FSDT Live Update, and try again.
