I have mean directly from Microsoft not from TDF.

I think that is not a big problem, the most have an Internet connection (and 
many App can't install without connection), but when not the installer gives a 
hint (only when needed), and the user should install the redist.

But any way, this is only a  suggestion, and has also weakness  (e. g. MS 
changes the link), the other case we have always up to date the vc_redist.exe.

Hi Juergen,

thanks for feedback!

Well, the main problem here is that there's no "latest vc_redist.exe" 
static link on MS site. So, this approach is simply impossible without us 
creating a redirect on our side. And this would create additional
problems:

1. Creating a redirect at TDF side imposes additional load to our server 
infrastructure; 2. Users will depend on reliability of TDF servers wrt this (in 
terms of their state, correctness of the link, and also possible 
man-in-the-middle problems with modified links pointing to malware) - note that 
LO downloads themselves are served from multiple mirrors, but this kind of 
redirection can't work using mirrors; 3. Users would need internet connection 
at time of setup (which might not be there: many download the installer, to 
bring it somewhere where there's no Internet connection).

So this is just not an option - at least, this is much worse than suggestion to 
simply telling people to manually download and install the redistributable 
themselves, put on the download page.

No; this is absolutely normal - most softwares out there behave this way, so 
not different from usual. Of course, *if* your suggestion was possible to be 
implemented in a reasonable way, it would be best - but the downsides outweigh 
the benefit.
