Problem:
During the installation of a SeeYou upgrade the installation fails with the description ‘MoveFile failed Code 5. Access denied.’. Sometimes also ‘An error occurred while trying to rename a file in the destination directory’.
This happens if you are running a new installation file on your PC while SeeYou is still running in the background.
Solution:
Close SeeYou before attempting to upgrade.
If it appears that SeeYou is not running but you still get this error reboot your computer then install the upgrade again.
