Tip #1: Whitelist the Skillmill domain and app on your firewall. Here's how:
Whitelisting with the Windows Firewall
To manage the whitelist in the Windows Firewall, click Start, type firewall and click Windows Firewall. Click Allow a program or feature through Windows Firewall (or, if you’re using Windows 10, click Allow an app or feature through Windows Firewall).
On the next screen, click Change settings, then tick or untick the box next to an item to allow or block it. In this case, make sure the box to the left of Skillmill is ticked. On the right, tick both the Private and Public columns.
After clicking Ok to apply the settings, open the Skillmill app and launch a scenario. You should be able to play through the scenario.
If the error message appears again, follow the steps below to turn off the firewall.
Tip #2: Turn off firewall. A firewall may be set up on your computer which is preventing you from downloading updates.
How to check firewall status:
You can check your firewall status at any time within Windows. Click Start at the lower left corner of your screen. Click Control Panel in the column on the right side of the menu. Check the value next to Windows Firewall to determine if a firewall is turned on. If on, turn the firewall off.
Interplay's Windows Application Internet Requirements Interplay's Windows Application requires a connection to the Internet to operate. It retrieves its simulation content from remote servers. It also communicates with servers to update user progress. It will run without any security changes needed on a regular Windows 10 setup. However, if your organization uses firewall software, there are a number of domains that will need to be whitelisted in order for the software to work. Those domains are listed below. It communicates with all of these domains over an https connection.
Domains that need whitelisting assets.interplay-learning.com.s3-us-west-1.amazonaws.com s3-us-west-1.amazonaws.com/assets.interplay-learning.com s3-us-west-2.amazonaws.com/windowsapp.interplaylearning.com api.interplay-learning.com platform-151821.appspot.com asset-gallery.appspot.com If you are going to be using HTC Vive Virtual Reality equipment please also whitelist the following domains: steamvr.com steamcommunity.com Is there an IP range to whitelist? We use Amazon S3 and Google App Engine cloud services for our servers. There is not an IP range that will remain constant for firewall rules. Amazon S3 is a very large service and does not regularly publish specific IP ranges in use. It is shared service made up of thousands of underlying nodes. In general AWS discourages relying on IPs as a form of security. Google App Engine End users on different ISPs or geographic locations might use different IP addresses to access the same App Engine application. DNS might return different IP addresses to access App Engine over time or from different network locations. Outbound Google App Engine instances make use of a large pool of IP addresses. The IP address ranges in this pool are subject to routine changes. In fact, two sequential API calls from the same application may appear to originate from two different IP addresses.
Folder Whitelisting for Antivirus If they experience issues with downloading or running the app, they can try whitelisting these folders through their anti-virus `C:\Users\<USERNAME>\AppData\Local\SkillMill` and `C:\Users\<USERNAME>\AppData\LocalLow\Interplay Learning`
