This is clearly a problem on your end, using the "wrong" browser and then not getting the correct file can't be a user/client issue. I also verified it happening in a different browser (Chrome 96.0.4664.110, Edge 96.0.1054.62).
Besides, I really don't care that much about it, as it is probably the same executable ("Start11_setup.exe") delivered when selecting the trial version anyway. This was just feedback so you can fix a bug on your website, but I am really baffled by the amount of incompetency here. The HTML delivered by your server, over a secure HTTPS connection to my browser is your responsibility, not user responsibility. Namely the HTML is as follows:
<a id="_Content__Products__CategoryRepeater__ProductsRepeater_0__DownloadGroupsRepeater_2__DownloadsRepeater_0__Link_0" class="bvlbutton blue" data-version="Latest" data-filesize="" data-comment="" data-filename="Start11 5-pack" data-changelog="" data-status="" href="../Controls/myaccount/This%20product%20is%20not%20yet%20available." data-hasqtip="6" aria-describedby="qtip-6">Download</a>
