My computer won’t allow download of AOS Anterior?

AOS Anterior application is a “trusted source” application and will download easily onto most laptops or pc’s, however if your computer has additional security installed or you are part of a networked system then you may find that access to download the software is denied. This is normally due to the “permissions” or firewall settings on the additional security not allowing the download of external applications. This is not an issue with the software. To download, you either need to “allow permissions” or click “more details” and then click “run or install anyway”. For networked systems you will need to get IT to remove the restriction for the application to download. If you continue to have issues please contact us for additional support via the form above.
