Sage 300 ERP Application Installer. A code download error has occurred.

Very often, after installing Sage 300 ERP on a new system, I’ve been presented with the following error messages when trying to open an icon within the Sage Desktop itself:

The easiest solution is obviously to switch off User Account Control before installing and leaving it off but this is not very secure and kind of defeats the whole purpose of User Account Control in the first place. And trust me, there are a lot of users out there where you definitely want to keep this in place.

So, how do we solve it. The solution is actually quite simple:

Open Control Panel and select Internet Options

On the Security Tab click on Local Intranet and then Sites:

Select Advanced:

Add your server name:

Press close and ok. You should now be back at the Security Tab.

Change the security level for this zone from it’s default to Low and press OK.

I had thought about using Trusted Sites but there are chances that other sites outside of your or your clients control will be specificied here as well. I personally would not set Trusted Sites to Low for that reason.

If you’ve come across this problem before and or have solved it in a different way I’d love to hear about it in the comments section below!
