The directory names are so awkward because they are caches. When CAT
gets updated with changes to actual installer code, all caches get
purged and recreated on the next download click. The name of the cache
directory changes as well.

There are more conditions which would lead to changes, e.g. if you make
a change to your IdP name, then the filename of the exe file itself
would change, and no amount of care on our side would prevent that.

So, in short, right now it's unreliable to deep-link directly to the
transient exe. I would suggest to link to this:

https://cat.eduroam.org/?idp=337&profile=487

which avoids the discovery process and drops your users directly into
the University of Hertfordshire download area. The Win 7 installer is
then just one click away.

Otherwise, you are of course invited to download the exe file yourself
and put it on persistent storage such as your own helpdesk pages on your
own webserver. Doing so will unfortunately mean you miss any updates to
the installer code which might happen when the CAT code gets updated.

I'll have a chat with my co-developer Tomasz to see if we can add a
little more persistence to the download directory structure for version
1.1. The problem with name changes will always remain though.

Greetings,

Stefan Winter
