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 

1. Creating a redirect at TDF side imposes additional load to our server 
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.

> In the current way it is possible you install older one of the dll's, and after the LO installation it pop up the Windows-Update, that I think is a little bit strange.

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.
