Hello Thomas and welcome to our forums,
I have tested this just down and everything worked as expected on my end.
I can think of few scenarios which I will more into in the lines to come:
1. You do not provide a direct download link for the MSI.
Let's consider Advanced Installer in our case. If you go to the "Downloads" page of Advanced Installer:
https://www.advancedinstaller.com/download.html
You will notice that the download does not automatically start. You will have to click on the
"Download" button in order for the download to start.

However, please note that, if you provide this link to Advanced Installer, it will not know to download the file.
Therefore, we must provide an automatic download link. For instance, if you click on the
"Download" button and then go to
"History" -->
"Downloads" (CTRL+J in Chrome), you will be able to see the automatic download link there:

As you can see, the links are different.
Obviously, this is just an example. Hope this makes sense.
2. Make sure that there is not any firewall rule that may be blocking the executable from downloading the MSI file.
3. Similar to the second point, make sure that there is not any AntiVirus software that blocks the executable from downloading the MSI file.
Hope this helps.
Best regards,
Catalin
