'Not commonly downloaded' popup when downloading an installation file

ChrisTrains installation files are not digitally signed, so some antivirus programs and browsers will pop up a message indicating that the program could be 'harmful' or 'dangerous'.

The picture below shows some examples of the popup on different systems:

In most cases there is an option to 'allow', 'proceed' or 'ok' a download. This is the option you should use.

ChrisTrains installers are all virus scanned before being placed on the webshops and there should be no problems downloading them and using them.

This message is merely because the installation files are not digitally signed.
